bookWriting Your First JavaScript Code

Now that you can run JavaScript on your computer, it's time to write simple code.

JavaScript allows you to store values and perform operations with them.

For example:


              
123456

            
const a = 5;
const b = 3;

const sum = a + b;

console.log(sum);
copy

Here, values are stored in variables. Then a calculation is performed, and the result is printed to the console.

You can also work with text:


              
123

            
const name = "John";

console.log(name);
copy

JavaScript executes code line by line. Each instruction runs in order, and you can use console.log to see the result at any step.

This is the foundation of programming: storing data, processing it, and producing an output.
