    Did you know that Unicode has a symbol for "really equals, but this time I mean it"? It could come in handy for JavaScript

    U+003D = EQUALS SIGN
    U+2261 ≡ IDENTICAL TO
    U+2263 ≣ STRICTLY EQUIVALENT TO

        @lcamtuf Bet you guessed this, but these can mean different things 🙂 For example, in number theory / cryptography, ≡ is used to denote that two numbers are the same modulo some fixed integer.

          @lcamtuf If PHP was created today they would teach you to only use ≣≡≣ to compare strings, the regular ≡ would pass them unquoted in bash scripts
