  • GitHub repo wtfjs

    🤪 A list of funny and tricky JavaScript examples

    Project mention: It's my first time interviewing web developers, what should I ask? | | 2021-10-05

    It’s very clearly a gotcha, if you’re into JS you also know it’s fucking weird and has a lot of illogical behaviour. There are thousands of examples of JS quirks out there. If I was presented with a question like this I could reason my way to a logical answer, but I would be questioning the interviewers motives and whether they are trying to trip me up with a gotcha.

    Project mention: In search of the perfect URL validation regex (2010) | | 2021-09-25

    Here’s a polyfill for the JS URL() interface which should give you a taste: (I tried finding the one in Firefox but I couldn’t actually work out where it started, this one is much easier to follow)

    TLDR: with a traditional parser, a big state machine that steps through the URL character by character and tokenizes it into the relevant pieces.

    Project mention: Enumerating and analyzing 40 non-V8 JavaScript implementations | | 2021-09-22

    I am astonished at the omission of ChakraCore, open sourced by Microsoft but sadly abandoned by them after they switched Edge to Chromium: But it looks like it’s still chugging along as a community effort rather than being completely abandoned.

    Project mention: Libre Endowment Fund: Sustainable Development of Free Software | | 2021-10-09

    There is a presentation at FOSDEM 2021 about FDL:

    Title: Give open source a (tax) break

    Cash that gets into FDL/LEF is then spent to sponsor existing FLOSS projects or to acquire intellectual property rights of existing works and change their license to FLOSS.

    Case 1: got financed partly by FDL/LEF

    Case 2: the radio hardware of the Open Radio Station (a 4G/5G vRAN base station based on Amarisoft stack and SlapOS) is in the process of being acquired and released as open source hardware. See

    The requirement for PhD is here to ensure that all projects that are financed by FDL/LEF have some kind of general interest or innovation, something which is useful to comply with Tax Law

    :rabbit2: Fastest possible memoization library

    Project mention: Forever Functional: Memoizing Functions for Performance | | 2021-05-16

    This is generic enough and we can use it for all functions, no matter how many parameters they expect -- it would even work with functions with a variable number of parameters; can you see why? Our memoization function is quite efficient, also, but if you need memoization in your code, you'd do even better by using fast-memoize, which boasts of being the speediest available memoizer; you can read how it was written in How I wrote the world's fastest JavaScript memoization library by Caio Gondim.
