map_function_usage.js

let list = [1,2,3,4,5];
let newList = []; // [2,3,4,5,6]

// we can use a map function to achieve this
// map function takes a callback function as an argument
// and returns a new array

let result = list.map(function(item) {
    return item + 1
})

console.log(result)


// for(let i = 0; i<list.length; i++) {
//     const newNunber = list[i] + 1;
//     newList.push(newNunber);
// }

// console.log(newList)
