javascript 运算符优先级

JavaScript 运算符优先级（从高到低） 

https://github.com/xhlwill/blog/issues/16

今天把js函数转换为python 函数时,发现在js运算符优先级这边卡了一下. 记录一下,以后注意

function C(A) {
return A < 62 ? String.fromCharCode(A += A < 26 ? 65 : A < 52 ? 71 : -4) : A < 63 ? '_' : A < 64 ? '$' : C(A >> 6) + C(A & 63)
}

等价转换js函数

function E(A){
if (A<62) {
if(A<26){return String.fromCharCode(A+65); }
else if(A<52){return String.fromCharCode(A+71);}
else {return String.fromCharCode(A-4);}
}

等价转换为python函数

def C(A):
    if A < 62:
        if A < 26:
            return chr(A + 65)
        elif A < 52:
            return chr(A + 71)
        else:
            return chr(A - 4)
    elif A < 63:
        return '_'
    elif A < 64:
        return '$'
    else:
        return (C(A >> 6) + C(A & 63))

else if(A<63){return '_';}
else if(A<64){return '$'}
else {return (E(A >> 6) + E(A & 63))}
}
