Emoji as a variable in js All In One

Emoji as a variable in js All In One

Math masters….where are you?!

If + = 20
and + = 16
and - = 4
then, + = _____

solutions

( + ) - ( - ) => ( + ) => ( + )
// 16 - 4 = 12

const   = 10;
const   = 6;
const   = 2;


  +   = 20 => 2 *   = 20
// 20 / 2 = 10

  +   = 16 =>   = 16 -  
// 16 - 10 = 6

  -   = 4 =>   =   - 4
// 6 - 4 = 2

unicode & emoji

Unicode ok ✅

const WTF = '什么鬼 ';
WTF;
// '什么鬼 '

const 什么鬼 = 'WTF ';
什么鬼;
// 'WTF '

emoji error ❌

const   = 'emoji ghost';
// ❌  Uncaught SyntaxError: Invalid or unexpected token

Unicode 8 ✅

Unicode 16 ❌

While ES6 brings stronger Unicode support to our beloved language, not all symbols can be used as valid identifiers. We can use things like var ಠ_ಠ = 42, but not var = 43.

虽然 ES6 为我们钟爱的语言带来了更强大的 Unicode 支持，但并非所有符号都可以用作有效标识符。我们可以使用 var ಠ_ಠ = 42 之类的东西，但不能使用 var = 43。

String. || !function() {
    var  = function() {
        try {
            var  = {},  = Object.defineProperty,  = (, , ) && ;
        } catch () {}
        return ;
    }(),  = String.fromCharCode,  = Math.floor,  = function() {
        var , ,  = 16384,  = [],  = -1,  = arguments.length;
        if (!) return "";
        for (var  = ""; ++ < ; ) {
            var  = Number(arguments[]);
            if (!isFinite() || 0 >  ||  > 1114111 || () != ) throw RangeError("Invalid code point: " + );
            65535 >=  ? .push() : ( -= 65536,  = ( >> 10) + 55296,  =  % 1024 + 56320, 
            .push(, )), ( + 1 ==  || .length > ) && ( += .apply(null, ), 
            .length = 0);
        }
        return ;
    };
     ? (String, "fromCodePoint", {
        "": ,
        "": !0,
        "": !0
    }) : String. = ;
}();
