Writing Your First JavaScript Code

Deslize para mostrar o menu

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);

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);

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.
