Question

Is it possible to convert a hexadecimal value to its respective ASCII character, not using the String.fromCharCode method, in JavaScript?

For example:

JavaScript:

0x61 // 97 
String.fromCharCode(0x61) // a

C-like:

(char)0x61 // a 

Answer 1

Not in that fashion, because JavaScript is loosely typed, and does not allow one to define a variable’s data type.

What you can do, though, is creating a shortcut:

var char = String.fromCharCode; // copy the function into another variable

Then you can call char instead of String.fromCharCode:

char(0x61); // a

Which is quite close to what you want (and perhaps more readable/requiring less typing).
