Variable

In web programming variables is a core concept that you will use everytime it allow you to store data (objects, functions, string, number, boolean..) that you can use, modify when you want in your code.

Declare variable

let name = "lucas";
let age = 23;
const calculateAge = () => {
    return age;
}
const Person = {};
let isAdult = true;

1. To declare your variable you have to use let or const keywords that indicate to the computer that we will create a variable.
2. This will create in memory and id that we can manipulate, reuse etc..
3. Notice that we use the ES6 syntax for declare our variables.
