ARRAYS

 // CREATION

let marks=[99,98,712,69,45];
let stds=["abhi","ash","bharath","vinay"];



// AN EMPTY ARRAY CAN ALSO BE CREATED
let emp=[];
console.log(emp.length);


//ACCESSING AN ARRAY CAN BE ACCOMPLISHED USING IT'S INDEX
console.log(marks[0]);
console.log(marks[3]);
console.log(stds[0]);



// LENGTH
console.log(marks.length);
console.log(stds.length);


//ARRAYS ARE MUTABLE
let fruits = ["mango", "banana", "grapes"];
fruits[0] = "oranges";
fruits[2] = "pineApple";
//AN ELEMENT CAN BE ADDED AT AN INDEX THAT CURRENTLY DOESNOT EXIST
fruits[10] = "Apples";
