javascript - Character representation from hexadecimal -

is possible convert hexadecimal value respective ascii character, not using string.fromcharcode method, in javascript?

for example:

javascript:

0x61 // 97  string.fromcharcode(0x61) // 

c-like:

(char)0x61 //  

not in fashion, because javascript loosely typed, , not allow 1 define variable's data type.

what can do, though, creating shortcut:

var char = string.fromcharcode; // copy function variable 

then can call char instead of string.fromcharcode:

char(0x61); // 

which quite close want (and perhaps more readable/requiring less typing).
