sir if a data is declared as a constant that means it will cannot be changed.but in Javascript course “Modify Array Data With Indexes”
Array is declared as a constant but still it is changes/modifying indexes…

Your code so far


// Setup
const myArray = [18, 64, 99];

// Only change code below this line
myArray[0]=[45];

It is an important thing to understand: you can’t change what the variable points to

const arr = [1]
arr = [2] //error

But you can change the array

const arr2=[1]
arr2[1] = 2;
arr2.push(3)

console.log(arr2) // [1, 2, 3]
