To add text-to-speech functionality to an HTML page, you can use the Web Speech API which provides two different synthesis voices to convert written text to sound. Here's an example of how to do it in JavaScript:

javascript
 
 
Copy code
const message = new SpeechSynthesisUtterance();

// set the text to be spoken
message.text = "Hello World!";

// create an instance of the speech synthesis object
const speechSynthesis = window.speechSynthesis;

// start speaking
speechSynthesis.speak(message);

You can also adjust the rate and pitch of the voice, as well as choose from different voice options. Here's a link to the MDN documentation on the Web Speech API which includes more examples and explanations: https://developer.mozilla.org/en-US/docs/Web/API/Web_Speech_API.

To add the variable from a function to your img src attribute, you can use JavaScript to access the img element and set its src attribute to the value of the variable. Here is an example code:

javascript
 
 
Copy code
// Assuming the image has an ID attribute of "myImage"
const myImage = document.getElementById("myImage");

// Your function that sets the variable
function setImageSource() {
  const myVariable = "path/to/image.jpg";
  return myVariable;
}

// Set the src attribute using the variable from the function
myImage.src = setImageSource();

In this example, the setImageSource function returns the path to your desired image. You can call this function to retrieve the variable and then set the src attribute of the img element to this variable using JavaScript.

In JavaScript, you can ignore space when comparing prompts by removing all the whitespace from both strings before comparing them. Here's an example code using .replace() function which replaces whitespace with empty string:

javascript
 
 
Copy code
let prompt1 = " How   to compare strings     ignoring   spaces  ";
let prompt2 = "How to compare strings ignoring spaces";

// Remove all white space from both strings
prompt1 = prompt1.replace(/\s/g, '');
prompt2 = prompt2.replace(/\s/g, '');

// Compare both strings without space
if (prompt1 === prompt2) {
  console.log("The prompts are the same ignoring spaces.");
} else {
  console.log("The prompts are different.");
}

This code removes all whitespace characters (spaces, tabs, and newlines) using the regular expression /\s/g with .replace() function. Then, it compares both strings without spaces using the === operator, which compares the values and the data types. In this example, the output would be "The prompts are the same ignoring spaces."

HTML:

code
 
 
Copy code
<img src="image-source-url" alt="image-description" style="width: 50%;">

CSS:

code
 
 
Copy code
img {
  width: 50%;
}

JavaScript: There are several ways to decrease the size of an image using JavaScript. Here's one example:

code
 
 
Copy code
const image = document.querySelector('img');
image.style.width = '50%';

Coding refers to the process of writing instructions for a computer to follow using a specific programming language. These instructions allow computers, applications, and other digital devices to perform tasks and solve problems. Examples of programming languages include Python, JavaScript, and C++.

The question mark symbol "?" in React is called the "conditional operator" or "ternary operator". It's a shorthand for an if-else statement. It can be used to render different content based on a condition. Here's an example in JavaScript:

javascript
 
 
Copy code
condition ? expressionIfTrue : expressionIfFalse

If the condition is true, the expressionIfTrue is executed, otherwise, the expressionIfFalse is executed.

Here's an example of how it can be used in a React component to render a different message based on a boolean state:

jsx
 
 
Copy code
function Example({ isLoggedIn }) {
  return (
    <div>
      {isLoggedIn ? <p>Welcome back!</p> : <p>Please log in.</p>}
    </div>
  );
}

In this example, if the isLoggedIn prop is true, it will render "Welcome back!" message, otherwise, it will render "Please log in." message.

To create a button, you can use HTML code. You can specify the button element using the button tag and add text inside it. For example:

html
 
 
Copy code
<button>Click me!</button>

This will create a simple button with the text "Click me!" inside it. You can also add attributes such as id and class to the button to style it or manipulate it with JavaScript. Here's an example with an id attribute:

html
 
 
Copy code
<button id="myButton">Click me!</button>

You can use CSS to style the button, and JavaScript to add functionality to it. Here's a link to a more detailed guide on how to create buttons in HTML: https://www.w3schools.com/tags/tag_button.asp
