Most efficient way of injecting line breaks
As part of a larger expression, I need to inject line breaks after each character in a string. I have something that works (hacked together from another post here), but was wondering if there is a more efficient method, since I’ll need to be doing this to multiple strings at once.
idx = 0;
outStr = "";
while (idx < value.length){
if (idx > 0) outStr += "\r";
outStr += value.substr(idx,1);
idx += 1;
}
outStr

Like this maybe:
value.replace(/.{1}/g, '$&\r') -
Brilliant! Thank you, Dan 🙏

How could I replace the hard-coded line break with a variable?
v = "\r";
And is there a good reference/directory for this type of syntax (i.e. “‘$&\r'”)?

Like this:
v = "\r";
value.replace(/.{1}/g, '$&' + v)Any good JavaScript + Regular Expression reference should do.

I thought I tried that, but I must have had a typo somewhere…works perfect! Thanks again.
