JavaScript code:

javascript
 
 
Copy code
const currentDate = new Date();
console.log(currentDate);

This code initializes a new Date object, which represents the current date and time. Then, it logs the current date to the console using the console.log() function.

In programming, logging refers to the process of recording or storing information or messages that help in understanding the behavior and execution of a program. It is a way to track the flow of the program and identify any issues or bugs. Typically, developers use logging to output messages to a console or a log file, which can be helpful for debugging and troubleshooting.

Logging can be done in various programming languages, such as JavaScript, Python, or Java. Here's an example of how logging can be used in JavaScript:

javascript
 
 
Copy code
console.log("This is a log message"); // Outputs the log message to the console

By logging important information, developers can gain insights into what their program is doing, monitor its performance, and identify and fix any errors or issues.

1. To log the current date, you can use the Date() object and its getDate() method to get the current day of the month, getMonth() method to get the current month (remember that months start from 0, so you need to add 1 to get the actual month number), and getFullYear() method to get the current year.

code
 
 
Copy code
console.log(new Date().getDate());

1. To log the number of milliseconds in the current time, you can use the Date() object and its getTime() method. This method returns the number of milliseconds since January 1, 1970.

code
 
 
Copy code
console.log(new Date().getTime());

1. To log the current day, you can use the Date() object and its getDay() method. This method returns an integer representing the day of the week. Remember that it starts from 0 for Sunday.

code
 
 
Copy code
console.log(new Date().getDay());

1. To log the current year, you can use the Date() object and its getFullYear() method. This method returns the current year.

code
 
 
Copy code
console.log(new Date().getFullYear());

1. To log the current month, you can use the Date() object and its getMonth() method. This method returns an integer representing the month, starting from 0 for January.

code
 
 
Copy code
console.log(new Date().getMonth());

1. To display the current date in the desired format, you can use the methods mentioned earlier to get the current day, month, and year. You can then use the toLocaleString() method to format the date as desired.

code
 
 
Copy code
const currentDate = new Date();
const day = currentDate.toLocaleString('en-US', { weekday: 'long' });
const month = currentDate.toLocaleString('en-US', { month: 'long' });
const date = currentDate.getDate();
const year = currentDate.getFullYear();

console.log(`Today is ${day}, ${month} ${date}, ${year}`);

1. To create the formatDate function as described, you can use similar logic as before to retrieve the current day, month, and year. You can then use template literals to format the date string.

javascript
 
 
Copy code
function formatDate(date) {
  const day = date.toLocaleString('en-US', { weekday: 'long' });
  const month = date.toLocaleString('en-US', { month: 'long' });
  const dateNumber = date.getDate();
  const year = date.getFullYear();

  return `${day}, ${month} ${dateNumber}, ${year}`;
}

console.log(formatDate(new Date()));

JavaScript:

javascript
 
 
Copy code
console.log(Date.now());

javascript
 
 
Copy code
console.log("Temperature on Monday is 18 degrees");
console.log("Temperature on Tuesday is 20 degrees");
console.log("Temperature on Wednesday is 22 degrees");
console.log("Temperature on Thursday is 19 degrees");
console.log("Temperature on Friday is 17 degrees");
console.log("Temperature on Saturday is 16 degrees");
console.log("Temperature on Sunday is 21 degrees");

Note: This is just an example. Please replace the values with the actual temperature if available.

html
 
 
Copy code
<!-- Create a HTML container to display the logs -->
<div id="temperature-logs"></div>

javascript
 
 
Copy code
// Store the temperature values in an object
const temperature = {
  monday: 18,
  tuesday: 20,
  wednesday: 22,
  thursday: 19,
  friday: 17,
  saturday: 16,
  sunday: 19
};

// Get the reference to the HTML container
const temperatureLogs = document.getElementById('temperature-logs');

// Loop through the object to log the temperature values for each day
for (const day in temperature) {
  const message = `Temperature on ${day} is ${temperature[day]} degrees`;
  temperatureLogs.innerHTML += `<p>${message}</p>`;
}

css
 
 
Copy code
/* Style the HTML container */
#temperature-logs {
  background-color: #f9f9f9;
  padding: 20px;
  border: 1px solid #ddd;
  border-radius: 5px;
  font-size: 16px;
  margin: 20px;
}

/* Style the log message */
#temperature-logs p {
  margin: 5px 0;
}

To log the current year in JavaScript, you can use the built-in Date() object to create a new date instance and use the .getFullYear() method to retrieve the current year. Here's an example:

javascript
 
 
Copy code
const currentYear = new Date().getFullYear();
console.log(currentYear); // logs the current year to the console

Output:

code
 
 
Copy code
2021 // depending on the current year

To log every day of the week with a temperature statement in JavaScript, you can create an array of strings for the days of the week, and then loop over the array to log each day with the corresponding temperature. Here's an example code block:

javascript
 
 
Copy code
const temperatures = [18, 20, 22, 19, 17, 21, 23]; // array of temperatures for each day

const daysOfWeek = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday']; // array of days of the week

for (let i = 0; i < daysOfWeek.length; i++) {
  console.log(`Temperature on ${daysOfWeek[i]} is ${temperatures[i]} degrees`);
}

This code defines two arrays: temperatures containing the temperature for each day of the week and daysOfWeek containing the name of each day. The loop iterates over the daysOfWeek array and logs a string for each day, using string interpolation to include the corresponding temperature. The resulting output would be:

code
 
 
Copy code
Temperature on Monday is 18 degrees
Temperature on Tuesday is 20 degrees
Temperature on Wednesday is 22 degrees
Temperature on Thursday is 19 degrees
Temperature on Friday is 17 degrees
Temperature on Saturday is 21 degrees
Temperature on Sunday is 23 degrees

javascript
 
 
Copy code
// Object with City Temperature
const paris = {
  temperature: 20 // Temperature in Celsius
}

// Log temperature of Paris
console.log(paris.temperature);

The output on the console will be 20.

To log the current date in JavaScript, you can use the Date object and its toLocaleDateString() method.

javascript
 
 
Copy code
const currentDate = new Date().toLocaleDateString();
console.log(currentDate);

This will output the current date in the local format of the current timezone. For example, if executed on October 15th, 2021, the output could be 15/10/2021.

To log milliseconds in JavaScript, you can use the getMilliseconds() method that returns the milliseconds of a given Date object.

javascript
 
 
Copy code
const date = new Date();
console.log(date.getMilliseconds());

This will output the current milliseconds in the console. If you want to log milliseconds for a specific date, you can pass the date as an argument to the Date constructor.

Example:

javascript
 
 
Copy code
const date = new Date("2022-01-01T10:30:00.500Z");
console.log(date.getMilliseconds());

This will output 500 in the console, representing the milliseconds of January 1st, 2022 at 10:30:00.500 UTC.

javascript
 
 
Copy code
// creating the weekDays array
const weekDays = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday'];

// console logging the array
console.log(weekDays);

To use console.log() in JavaScript, simply type console.log() in your code followed by the message you want to log. For instance, console.log("Hello, world!");. When your code runs, it will print the message to the console. This is particularly useful for debugging your code, as you can see the values of variables or check if a certain line of code has executed properly.

Here's an example of how you can use console.log() in JavaScript:

javascript
 
 
Copy code
let myVariable = "Hello, world!";
console.log(myVariable);

This will output "Hello, world!" to the console. You can also log multiple variables or messages by separating them with commas in the console.log() function:

javascript
 
 
Copy code
let variable1 = "SheCodes";
let variable2 = 5;
console.log("Welcome to", variable1, "Intro Workshop", variable2);

This will output "Welcome to SheCodes Intro Workshop 5" to the console.

The following code creates an array containing 3 Australian city names and logs each name:

javascript
 
 
Copy code
var australiaCities = ['Sydney', 'Melbourne', 'Brisbane'];

australiaCities.forEach(city => {
  console.log(city);
});

console.log() is a function in JavaScript that outputs a message to the console of a web browser.

Example:

javascript
 
 
Copy code
console.log("Hello World")

This code would output "Hello World" to the browser console.

JavaScript

javascript
 
 
Copy code
let today = new Date();
console.log(today);

Output: Mon Mar 09 2020 13:14:37 GMT+0000 (Greenwich Mean Time)

javascript
 
 
Copy code
var city = 'New York';
var country = 'United States';

console.log(`I am from ${city}, ${country}.`);

javascript
 
 
Copy code
let month = new Date().getMonth();
console.log(month);

javascript
 
 
Copy code
const date = new Date();
const year = date.getFullYear();

console.log(year);

Using JavaScript, you can log the current day using the Date() function:

javascript
 
 
Copy code
const today = new Date();
console.log(today);

You can also use the toDateString() method to get the current date in the Day Mon Date format, e.g. Tue Mar 16:

javascript
 
 
Copy code
const today = new Date();
console.log(today.toDateString());

javascript
 
 
Copy code
console.log(new Date());

This code will output the current date, for example: Tue Apr 21 2020 11:12:26 GMT+0100 (British Summer Time).

javascript
 
 
Copy code
const weekdays = ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"];

console.log(weekdays); // logs ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"]

weekdays.splice(0, 2);

console.log(weekdays); // logs ["Wednesday", "Thursday", "Friday", "Saturday", "Sunday"]

To show the word length in JavaScript, you can use the .length property. For example:

js
 
 
Copy code
let word = "Shecodes"
let wordLength = word.length;
console.log(wordLength); 

This code would output 8, as that is the length of the word.

You can log the number of milliseconds in the current time with the following code:

javascript
 
 
Copy code
const currentMilliseconds = Date.now();
console.log(currentMilliseconds);

You can add an ID to an <li> element and log it with the following code:

javascript
 
 
Copy code
const listElement = document.querySelector('li');
listElement.id = 'my-element';
console.log(listElement);
