Is there any function which adds 1 to the array element? [closed]

Question

I have a given array like this let arr1 = ['a','b','c'];

And I want output like this ['a1','b1','c1']

Which function should I use?

Answer 1

For this task, the map function is the best candidate. It generates a new array by applying the function given as argument to each element.

let arr1 = ['a','b','c'];
console.log(arr1.map(x=>`${x}1`));
