How to deal with dirty side effects in your pure functional JavaScript
How to deal with dirty side effects in your pure functional JavaScript So, you’ve begun to dabble in functional programming. Once you’ve started, it won’t be long before you come across pure functions. And, as you go on, you will discover that functional programmers appear to be obsessed with them. “Pure functions let you reason about your code,” they say. “Pure functions are less likely to start
Proxy - JavaScript | MDN
The Proxy object enables you to create a proxy for another object, which can intercept and redefine fundamental operations for that object. The Proxy object allows you to create an object that can be used in place of the original object, but which may redefine fundamental Object operations like getting, setting, and defining properties. Proxy objects are commonly used to log property accesses, val

User-centric performance metrics Stay organized with collections Save and categorize content based on your preferences. We've all heard how important performance is. But when we talk about performance, and about making websites "fast", what specifically do we mean? The truth is that performance is relative: A site might be fast for one user (on a fast network with a powerful device) but slow for a

var functionName = function() {} vs function functionName() {}
I've recently started maintaining someone else's JavaScript code. I'm fixing bugs, adding features and also trying to tidy up the code and make it more consistent. The previous developer used two ways of declaring functions and I can't work out if there is a reason behind it or not. The two ways are: var functionOne = function() { // Some code }; And, function functionTwo() { // Some code } What a

Browserify
Browsers don't have the require method defined, but Node.js does. With Browserify you can write code that uses require in the same way that you would use it in Node. Here is a tutorial on how to use Browserify on the command line to bundle up a simple file called main.js along with all of its dependencies:

WebModule は JavaScript で部品を作るための金型であり、巨大な建造物を安全に建築する方法を示した工法(フォーマット)です。 環境に応じてダイナミックに変化する部分(コードやフォーマット)に重きを置かず、より抽象的でソリッドな部分(エンジニアリングの哲学)を軸足としたマイクロフレームワークでもあります。 哲学が存在しない世界では何が起きたか。何が起きているか あなたは、そびえ立つ九龍城のように、継ぎ足し継ぎ足しが繰り返され、「もう一体どこから手を付けたら…」 「なぜ動いているのか不思議」 なコードの山と対峙し、途方に暮れた事はありませんか? そして 「テストは無い」 「自動テストはないが人力テストはある」 「人力なのでテストに丸々3日かかる。そしてコツが要る」 と言われたり、「設計? ありませんよ? コードがドキュメントです、だってドキュメントをメンテするの大変じゃないで
