Click on the black bar that appears at the bottom of the page to open your collection.
In your collection, you will see a section called "Embed" with a code snippet. Copy that code snippet.
Open your HTML file or your CSS file if you are using an external stylesheet.
Paste the code snippet inside the <head> section of your HTML or at the top of your CSS file.
Save your HTML or CSS file.
Example:
html Copy code
<head>
...
<link href="https://fonts.googleapis.com/css?family=Open+Sans&display=swap" rel="stylesheet">
...
</head>
By following these steps, you will be able to add a Google Font to your website. Remember to replace "Open+Sans" with the name of the font you want to use.
what does .classList.add do?
.classList.add is a method in JavaScript that adds one or more class names to the specified element. It takes one or more arguments (class names) and adds them to the class attribute of the element. Here's an example in JavaScript:
js Copy code
let element = document.querySelector('h1');
element.classList.add('large', 'bold');
In the example above, the classList.add method adds the class names large and bold to the class attribute of the h1 element. Now, the element will have the classes large and bold, which you can use to apply CSS styles to the element.
You can find more information about classList.add and other methods in the classList API in the following link: https://developer.mozilla.org/en-US/docs/Web/API/Element/classList
create polygon with lines and add them in a table with data of user, date and hour, the action include create or add polygon and a option for remove the row of table
jsx Copy code
import React, { useState } from "react";
const PolygonTable = () => {
const [rows, setRows] = useState([]);
const handleCreatePolygon = () => {
// logic to create a polygon with lines
// ...
const date = new Date();
const newRow = {
user: "John Doe",
date: date.toLocaleDateString(),
hour: date.toLocaleTimeString(),
action: "Create Polygon"
};
setRows([...rows, newRow]);
};
const handleAddPolygon = () => {
// logic to add a polygon with lines
// ...
const date = new Date();
const newRow = {
user: "Jane Smith",
date: date.toLocaleDateString(),
hour: date.toLocaleTimeString(),
action: "Add Polygon"
};
setRows([...rows, newRow]);
};
const handleRemoveRow = (index) => {
const newRows = [...rows];
newRows.splice(index, 1);
setRows(newRows);
};
return (
<div>
<button onClick={handleCreatePolygon}>Create Polygon</button>
<button onClick={handleAddPolygon}>Add Polygon</button>
<table>
<thead>
<tr>
<th>User</th>
<th>Date</th>
<th>Hour</th>
<th>Action</th>
<th></th>
</tr>
</thead>
<tbody>
{rows.map((row, index) => (
<tr key={index}>
<td>{row.user}</td>
<td>{row.date}</td>
<td>{row.hour}</td>
<td>{row.action}</td>
<td>
<button onClick={() => handleRemoveRow(index)}>Remove</button>
</td>
</tr>
))}
</tbody>
</table>
</div>
);
};
export default PolygonTable;
This is a React component that renders a table with the user data, date, hour, and action. 2 buttons (Create Polygon and Add Polygon) are provided to create and add new polygons respectively. A Remove button is available in each row to remove the particular row from the table. When any action is performed, a new row is added to the table with the current user, date, time, and action.

jsx Copy code
import React, { useState, useEffect, useRef } from "react";
const PolygonTable = () => {
const [rows, setRows] = useState([]);
const [canvasWidth, setCanvasWidth] = useState(500);
const [canvasHeight, setCanvasHeight] = useState(300);
const canvasRef = useRef(null);
useEffect(() => {
const canvas = canvasRef.current;
const ctx = canvas.getContext("2d");
// logic to handle canvas drawing
// ...
return () => {

const date = new Date();
const newRow = {
user: "John Doe",
date: date.toLocaleDateString(),
hour: date.toLocaleTimeString(),
action: "Create Polygon"
};

<td>{row.hour}</td>
<td>{row.action}</td>
<td>
<button onClick={() => handleRemoveRow(index)}>Remove</button>
</td>
</tr>
))}
</tbody>
</table>
<canvas
ref={canvasRef}
width={canvasWidth}
height={canvasHeight}
style={{ border: "1px solid black" }}
/>
</div>
);
};
export default PolygonTable;
This is an updated version of the previous component that adds a space for the user to draw polygons. The canvas element is added to the component, and its size is determined by the canvasWidth and canvasHeight states.
A useEffect hook is used to handle the logic of drawing polygons inside the canvas. The cleanup logic is also included in the useEffect hook.
Note that the actual logic to handle drawing the polygons is missing as it will depend on your use case.
How to add 10 years using moment.js
To add 10 years using moment.js, you can use the add() function and pass in 10 as the first parameter and 'years' as the second parameter. Here is an example code snippet in JavaScript:
javascript Copy code
// current date
const currentDate = moment();
// add 10 years
const newDate = currentDate.add(10, 'years');
console.log(newDate); // prints the new date with 10 years added
You can learn more about moment.js and its documentation here: https://momentjs.com/docs/
what is a .push
.push() is a function in JavaScript that adds one or more elements to the end of an array and returns the new length of the array. Here's an example:
javascript Copy code
let fruits = ["apple", "banana"]; // declare an array
fruits.push("orange"); // add "orange" to end of array using push
console.log(fruits); // output: ["apple", "banana", "orange"]
In this example, the push() function adds the element "orange" to the end of the fruits array.
how to add - between words in javascript
You can add a dash ("-") between words in JavaScript by using the replace() method along with a regular expression.
Here's an example of how to replace all spaces with dashes:
javascript Copy code
const myString = "hello world";
const stringWithDashes = myString.replace(/\s+/g, "-");
console.log(stringWithDashes); // Output: "hello-world"
In the code above, the replace() method is called on the myString variable. The first argument is a regular expression /s+/g which matches all whitespace characters (including spaces, tabs, and newlines) globally ("g" flag). The second argument is the replacement string, in this case, a dash "-".
This code will replace all spaces in the original string with dashes, and output "hello-world".
what does .push mean? Can you explain in the most simplest way
.push is a JavaScript array method used to add new elements/objects at the end of an array. It modifies the original array and returns the new length of the array.
Here is an example usage:
javascript Copy code
const fruits = ['apple', 'banana', 'kiwi'];
fruits.push('orange');
console.log(fruits); // ['apple', 'banana', 'kiwi', 'orange']
In the above example, fruits.push('orange') added 'orange' at the end of the fruits array. Now the new length of the array is 4, so it will log ['apple', 'banana', 'kiwi', 'orange'] in the console.
add a new class to an element from html in JS
You can add a new class to an element in HTML using JavaScript by selecting the element with the querySelector method, and then using the classList property to add a new class with the add method. Here's an example:
javascript Copy code
// HTML:
// <div id="myDiv" class="old-class"></div>
// JavaScript:
const myDiv = document.querySelector('#myDiv');
myDiv.classList.add('new-class');
In this example, we first use querySelector to select the div element with the ID myDiv. Then, we use the classList.add method to add the class new-class to the element. Now the HTML looks like this:
html Copy code
<div id="myDiv" class="old-class new-class"></div>
You can find more information about querySelector and classList in the following documentation:
how to use document.querySelector to change the name of the class of an element
To change the name of a class of an element using document.querySelector, you can use the classList property of the selected element which provides several methods to add, remove or toggle classes. Here's an example in JavaScript:
javascript Copy code
// select the element to change its class name
const myElement = document.querySelector('#my-element');
// use the classList property to modify the class names
myElement.classList.remove('old-class-name');
myElement.classList.add('new-class-name');
In this example, querySelector is used to select an element with an id of my-element. The classList property is then used to remove the class old-class-name and add the class new-class-name.
You can check out more information about the classList property on the MDN web docs: https://developer.mozilla.org/en-US/docs/Web/API/Element/classList
how to make nav bar menu to show on scrolling upward and disappear on scrolling downward
To make a nav bar menu show on scrolling upward and disappear on scrolling downward, you can use JavaScript and CSS.
First, you need to add an event listener to detect when the user scrolls on the page. You can use the window.addEventListener function for this:
js Copy code
window.addEventListener('scroll', function() {
// code to be executed when user scrolls
});
Inside the function, you can check the window.scrollY property to see how far the user has scrolled from the top of the page. If the user has scrolled up (i.e. window.scrollY is less than the previous scroll position), you can add a CSS class to show the nav bar. If the user has scrolled down, you can remove the CSS class to hide the nav bar.
Here's an example of how you can achieve this:
js Copy code
// keep track of previous scroll position
let prevScrollPos = window.pageYOffset;
window.addEventListener('scroll', function() {
// current scroll position
const currentScrollPos = window.pageYOffset;
if (prevScrollPos > currentScrollPos) {
// user has scrolled up
document.querySelector('.navbar').classList.add('show');
} else {
// user has scrolled down
document.querySelector('.navbar').classList.remove('show');
}
// update previous scroll position
prevScrollPos = currentScrollPos;
});
In the example above, we add a .show class to the .navbar element when the user scrolls up, and remove it when the user scrolls down. You can define the .show class in your CSS to style the nav bar however you want.
Note that this is just one way to achieve this effect, and there are many other ways to do it depending on your specific needs.
what is a function in java script?
In JavaScript, a function is a block of code that defines an operation, can optionally receive input in the form of parameters, and can optionally return a value. For example, the following function named add takes two numbers as parameters, calculates their sum and returns it:
javascript Copy code
function add(num1, num2) {
return num1 + num2;
}
More information on functions can be found in the MDN JavaScript Documentation.
how to add a class to a html element in javaScript?
In JavaScript, you can add a class to an HTML element with the classList property. You can use the add() method to add a class to the classList property.
For example:
javascript Copy code
document.getElementById("myElement").classList.add("myClass")
This code retrieves the element with an ID of "myElement", then adds the class "myClass" to the classList property.
How do I add an image to HTML?
Adding an image to HTML is relatively simple. First, decide on the location of the image you'd like to use. You can either store the image file on the same server as your HTML document or reference an image file stored on a different server.
Once you have the source of the image, use the <img> element with the src attribute to define the source of the image. For example, if an image is stored in the same directory as the HTML file, you can use the following code to add it to the page:
html Copy code
<img src="example-image.jpg" alt="Example Image">
You can also use HTML code to control the size and position of the image. Further information can be found here.

Not likely. AI can automate tasks and make developers' jobs more efficient but it can't fully replace the human ability to deal with complex software. And AI will still require human developers to supervise and improve it further.
So developers may see their tasks change but they won't be replaced by AI. 👩💻🤝💻
