Answer 1

You could use slice . https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/slice

In your case, this should work:

a.slice(1, -1);

Answer 2

This can also help:

let a = 'hello'
a.substring(1, a.length - 1)

Answer 3

Use the javascript slice function.

a.slice(1, a.length)

Look up the javascript slice function.

Answer 4

Avoiding splice, slice, substring...

const word = 'hello'
const filtered =
  word
  .split('')
  .filter((x, i) => !(i === 0 || i === word.length - 1))
  .join('');

console.log(filtered)
