This post is part of my Today I learned series in which I share all my web development learnings.
Yoshua Wuyts tweeted that var let = 12 is valid JavaScript. Wat? It turns out let is no reserved word in JavaScript. If you want to dig deeper there is an interesting read on this topic, that was recently released on the Bocoup blog.
Edited: Turns out this is only true in sloppy mode. Thanks Robin!
