How to use this gist

You've got two main options:

On May 1, 2018, GitHub changed the suggested IP addresses to put on the A records for domains that use GitHub Pages. The new ones now support HTTPS for custom domains, but the old ones did not. Here are the old ones for historical purposes:

192.30.252.153
192.30.252.154

Here are the new ones:

185.199.108.153
185.199.109.153
185.199.110.153

Strings

`String.prototype.*`

None of the string methods modify this – they always return fresh strings.

charAt(pos: number): string ^ES1

Returns the character at index pos, as a string (JavaScript does not have a datatype for characters). str[i] is equivalent to str.charAt(i) and more concise (caveat: may not work on old engines).
