(JavaScript) JavaScript local storage - EvanHahn

Mon, 12 Mar 2012 10:02:38 UTC

Here's how to use this: * To access something in the local storage, type `Evan.local('name')`. You may need to use `JSON.parse()` on this result. Returns `null` if nothing's there. * To assign something in the local storage, type `Evan.local('name', value)`. * To remove something from the local storage, type `Evan.local('name', null)`. This may not work if private browsing is enabled (eg, on Safari for iOS).

This prepends a `#` if it's not already there. Useful when doing jQuery selectors.

(JavaScript) Make an empty object in JavaScript - EvanHahn

`Object.create(null)` is a more memory-efficient way to make objects, but it's not supported in all versions of JavaScript, so you can do the "old-fashioned" `{}` if that function isn't available.

(JavaScript) Is something undefined in JavaScript? - EvanHahn

Checking for `undefined` in JavaScript is weird (the variable can be redefined), so I made a function to do it. This stuff (and others) is also in my [JSTypes](https://github.com/EvanHahn/JSTypes) type-checking library.
