can I do .on value changed of a array code example
Example: modify array elements javascript
Using a FOR loop, write a function addNumber which adds the argument n to each
number in the array arr and returns the updated arr:
const addNumber=(arr, n)=>{
let arr1=[];
for(let i=0;i<Math.max(arr.length);i++){
arr1.push((arr[i]||0)+n)
}
return arr1;
}
console.log(addNumber([4, 5, 6], 7)); // expected log [11, 12, 13]
