Explain console.log in javascript

• console.log is a built-in function in JavaScript that allows you to output data to the console.

• The console is a feature in web browsers and some code editors that developers use to debug and test their code.

The basic syntax for console.log is:

    console.log(expression);

• Here, expression can be any valid JavaScript expression that you want to output to the console. 

For example, you could output a string:

    console.log("Hello, world!");

Or output the result of a calculation:

    console.log(2 + 2);

Or output the value of a variable:

    let name = "John";

    console.log(name);

• When you run your JavaScript code, the output of the console.log statement will be displayed in the console, usually below your code.

• This can be very helpful for debugging and understanding what your code is doing.

• console.log is a powerful tool for understanding the behavior of your code and identifying errors.

• You can use it to output values at different points in your code and see how they change as your program runs.

• You can also use it to test assumptions and verify that your code is working as expected.
