agar humne kisi array ke element ko chnage karna hai to hum fill ka use karte hain. or isme value,start,end argumnet dete hain
const array = [-1,-2,-3,-4]
array.fill(0,2,3);
console.log(array)
// value , start , end
// const myArray = new Array(10).fill(0);
// console.log(myArray);
const myArray = [1,2,3,4,5,6,7,8];
myArray.fill(0,2,5);
console.log(myArray);
