Learning JavaScript

Jez Williams

`Freelace creative front end developer 🤓`

Since graduating in computer science six years ago, I’ve found love in the creative side of the web. I’ve been freelancing for three years and enjoy being in new environments and learning new skills. Most recently, I’ve been building with React and progressing deeper into backend development to compliment my frontend skills.

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).
