const numbers = [1, 2, 3, 4, 5];
const bigNumbers = numbers.map(number => {

});//map() methods returns a new array

let inside_data = data.brands.map((i) => {
console.log(i); //dell acer asus
});const arr = [1, 2, 3, 4, 5, 6];
const mapped = arr.map(el => el + 20); //[21, 22, 23, 24, 25, 26]['elem', 'another', 'name'].map((value, index, originalArray) => {
console.log(.....)
});let myMap = new Map()
let keyString = 'a string'

// setting the values
myMap.set(keyString, "value associated with 'a string'")

myMap.size // 3
// getting the values
