Generate an array of alphabet characters

JavaScript

const alphabet = 'abcdefghijklmnopqrstuvwxyz'.split('')

// Or
const alphabet = [...'abcdefghijklmnopqrstuvwxyz']

// Or
const alphabet = Array(26)
  .fill(0)
  .map((_, i) => String.fromCharCode(i + 97))

// Or
const alphabet = [...Array(26).keys()].map((i) => String.fromCharCode(i + 97))

// Or
const alphabet = [...Array(26)].map((_, i) => (i + 10).toString(36))

// Or
const alphabet = String.fromCharCode(
  ...' '
    .repeat(26)
    .split('')
    .map((_, i) => i + 97)
).split('')

TypeScript

// Or
const alphabet: string[] = [...Array(26).keys()].map((i) => String.fromCharCode(i + 97))

// Or
const alphabet: string[] = [...Array(26)].map((_, i) => (i + 10).toString(36))

// Or
const alphabet: string[] = String.fromCharCode(
