Arrays.js

// arrays are used to store data of same data type at a single place
let cars = ["bmw" , "honda" , "toyota"];
console.log(cars[0]);
// prints bwm

// now how to add in the arrays
//push
let cars = ["bmw" , "honda" , "toyota"];
console.log(cars[0]);
cars.push("alfa romeo");
// added at the end

// Removing from the array
//pop
let cars = ["bmw" , "honda" , "toyota"];
console.log(cars[0]);
cars.pop();
// last will be removed

// adding at the start
let cars = ["bmw" , "honda" , "toyota"];
console.log(cars[0]);
cars.unshift("Suzuki");

// removing from the start
let cars = ["bmw" , "honda" , "toyota"];
console.log(cars[0]);
cars.shift("Suzuki");

// length of array
// removing from the start
let cars = ["bmw" , "honda" , "toyota"];
console.log(cars[0]);
console.log(cars.length);

// for loop of array
let cars = ["bmw" , "honda" , "toyota"];
console.log(cars[0]);
for (let i=0 ; i = cars.length ; i++){
    console.log(cars[i]);
}

// for...of loop of array
let cars = ["bmw" , "honda" , "toyota"];
console.log(cars[0]);
for (const car of cars){
    console.log(car);

// multiple objects can be stored in array also just by changning the brackets at the start

// annd for accessign it

//this will gives the marks of SE of student at the 0 index of arrays
