A Guide to Functional Programming Lingo for JavaScripters

A Guide to Functional Programming Lingo for JavaScripters

Functional programming gets a bad wrap about being too hard for mere mortals to comprehend. This is nonsense. The concepts are actually quite simple to grasp.

The jargon is the hardest part. A lot of that vocabulary comes from a specialized field of mathematical study called category theory (with a liberal sprinkling of type theory and abstract algebra). This sounds a lot scarier than it is. You can do this!

All examples using ES6 syntax. wrap (foo) => bar means:

function wrap (foo) {

Better local require() paths for Node.js

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

Possible solutions

Methods to flush the HTML5 Application Cache on iOS. In a UIWebView Webkit uses an sqlite database to store the resources associated to a cache manifest, as there is no API yet to flush the Application Cache you can use this method which delete entries directly from the database. However, this approach could break anytime if the implementation o…
static NSString *cacheDatabaseName = @"ApplicationCache.db";
static NSString *cacheGroupTable = @"CacheGroups";
static NSString *cacheGroupTableManifestURLColums = @"manifestURL";
static NSString *cacheTable = @"Caches";
static NSString *cacheTableCacheGroupId = @"cacheGroup";

Clears the cached resources associated to a cache group.
