Variables
Desliza para mostrar el menú
Variables are used to store data in your program.
Instead of repeating values everywhere, you save them in a variable and reuse them when needed.
In JavaScript, you will mostly use two keywords:
const: for values that should not change;let: for values that can change.
Example:
1234567const name = "Alex"; let count = 0; count = count + 1; console.log(name); console.log(count);
Here, name stays the same, while count can be updated.
Using the right type of variable helps you write clearer and more predictable code.
