[F8] Replacing character on a given position in a string

[walnoot]

Hi!

Is there a way to replace a character in a string based on it's given index?

Like:
you have:
"hello"

and you want to change character at position 3 to "a"

result:
"healo"

I'd rather don't want to change string into array first,
modify array and turn it into string again.

I hope there's a trick with slices, splits and/or joins ?
Thanks in advance!

does this method work for your project ?

function replaceChar(str,id,char){
len = str.length-1;
preTxt = str.substr(0,id-1); trace(preTxt); // he
endTxt = str.substr(id,len); trace(endTxt); // lo
newTxt = preTxt+char+endTxt; trace(newTxt); // healo
};

myStr = "hello";
replaceChar(myStr,3,"a")
