Arrays & Objects in JavaScript

objects

// let employee = {
        //     name: "Harry",
        //     salary: 10,
        //     channel: "CodeWithHarry",
        //     "channel 2": "ProgrammingWithHarry",
        // }
        // console.log(employee);

this is how we create an object

arrays

// let names = [1, 2, 4, "Harry", undefined];
        // let names = new Array(41, 2, 4, "Harry", undefined);

these are the two ways how we define an array

if we use a broken element in array the we will use it like "harr y"

we will enter it and call it in the same way

let names = new Array(23);

this will create  a new arrary of 23 empty elements

console.log(names.length);

this will give the length of the array

names = names.sort();

to sort elements in array

names.push("this is pushed");

names. 

to add elements in array
