How do I zip two arrays into one array of strings containing the values

Question

For instance, if I have two arrays that look like this:

var array1 = ['a','b'];
var array2 = [1, 1];

The output array should be:

var newArray = ['a:1', 'b:1']

Answer 1

You could use map like this:

var array1 = ['a','b'], array2 = [1, 1];
var newArray = array1.map((e, i) => `${e}:${array2[i]}`);

console.log(newArray);
