Python's string.ascii_letters in JavaScript

How to use

You you can install via yarn add locutus and require this function via const ascii_letters = require('locutus/python/string/ascii_letters').

It is important to use a bundler that supports tree-shaking so that you only ship the functions that you actually use to your browser, instead of all of Locutus, which is massive. Examples are: Parcel, webpack, or rollup.js. For server-side use this is typically less of a concern.

Examples

Please note that these examples are distilled from test cases that automatically verify our functions still work correctly. This could explain some quirky ones.

#	code	expected result
1	ascii_letters()	'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'

Here’s what our current JavaScript equivalent to Python's string.ascii_letters looks like.

module.exports = function ascii_letters() {
  //   original by: Yury Shapkarin (https://shapkarin.me)
  //   example 1: ascii_letters()
  //   returns 1: 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'

  const length = 26
  let i = 65

  return [...Array(length + 6 + length)]
    .reduce(function (accumulator) {
      return accumulator + String.fromCharCode(i++)
    }, '')
    .match(/[a-zA-Z]+/g)
    .reverse()
    .join('')
}

A community effort

Not unlike Wikipedia, Locutus is an ongoing community effort. Our philosophy follows The McDonald’s Theory. This means that we assimilate first iterations with imperfections, hoping for others to take issue with-and improve them. This unorthodox approach has worked very well to foster fun and fruitful collaboration, but please be reminded to use our creations at your own risk. THE SOFTWARE IS PROVIDED "AS IS" has never been more true than for Locutus.

Ehm.. only 5 Python functions?

We can use your help porting more. Have a rainy Sunday afternoon to spare and a taste for a porting puzzle?

• Get inspiration from the Python 3 standard library string page.
• Click "New file" in the appropriate folder on GitHub. This will fork the project to your account, directly add the file to it, and send a Pull Request to us.

We will then review it. If it's useful to the project and in line with our contributing guidelines your work will become part of Locutus and you'll be automatically credited in the authors section accordingly.
