Recently made the upgrade to Webpack 2 because I wanted the tree shaking functionality. Took about a day. Here are some tips, along with the results. https://medium.com/@jberniertech/upgrading-to-webpack-2-and-tree-shaking-results-e68bd203c974 (originally posted March 14, 2017)

Javascript is a funky language. Here are some obvious design flaws: **1. [Regex `test()` method is inconsistent when global flag is set](http://stackoverflow.com/questions/1520800/why-regexp-with-global-flag-in-javascript-give-wrong-results)** ``` var pattern = /hi/g; pattern.test('hi'); //true pattern.test('hi'); //false ``` Today at work I spent hours on a witch hunt trying to pinpoint the cause of a bug that was delaying a production release. It ended up coming down to this absurd Javascript quirk within a single "if" statement inside a portion of code that hadn't been touched in a year. **2. null and undefined** Having separate null and undefined types just adds unnecessary confusion. The best way to check whether variable is null or undefined is `if (varname == null)`. Using the triple equals (which is preferred in almost every other situation) will not catch both types. **3. typeof** ``` typeof [] //"object" typeof nul

This is a tutorial for beginners on how to set up a dev environment on a Mac/OSX (since you'll probably be using one as the primary laptop for your job). Text Editor - Sublime Text You'll probably want at least a text editor like [Sublime Text](https://www.sublimetext.com/). Install it, and then set up a `subl` keyword that you can use to launch Sublime from the terminal (eg. `subl filename.txt`)     sudo ln -s /Applications/Sublime\ Text.app/Contents/SharedSupport/bin/subl /usr/local/bin/subl Next, [install the package manager for Sublime](https://packagecontrol.io/installation). Then you'll want to install a [nice dark theme](https://github.com/buymeasoda/soda-theme). Terminal - iTerm, Oh My Zsh Download [iTerm2](https://www.iterm2.com/). It's much better than the Mac's stock terminal. Fire it up and install [Oh My Zsh](https://github.com/robbyrussell/oh-my-zsh) via the following command:     sh -c "$(curl -fsSL https://raw.githubuserconte
