A. JavaScript Refresher

Important information

Imports and Exports: I learned 3 different ways to import and export using JavaScript.

Differentes types of values:

• String
• Number
• Boolean
• Null & undefined
• Objects

In javascript in common:

let = create variables (local scoop)

var = create variables (global)

Array Functions:

• map: create new array with the values of the original array and you can add more

const = create constant

Functions and arrow functions

• function : hello(){ //code }
• arrow functions : ()=>{ //code }

Destructuring

const [firsName,lastName] = ["Max","Rodriguez"] const {name,lastName} = { name:"Max", lastName: "Rodriguez" }
