const name = ['John Doe', 'Jack Lock', 'Nick Load'];
const initials = name.map([a]) => a);
console.log(initials);

I'm trying to print array items initials, but I only got first letter of the items.

This is what I'm getting

What I need

['J.D', 'J.L', 'N.L']

So, instead of destructuring the string and getting the first char, get the full name, split on the whitespace and then get the first letter of each. — Gabriele Petrioli

I don't see how you get "P A I" from this code. The code isn't even trying to create any initials… — deceze

map() to loop over the array
split() to get first and last name
map() again over both names
substring() to get the first char
join() to concat again

const name = ['John Doe', 'Jack Lock', 'Nick Load'];

const initials = name.map(n => n.split(' ').map(s => s.substring(0, 1)).join('.'));

console.log(initials);

[
  "J.D",
  "J.L",
  "N.L"
]
