Eliminating the final character from a string using regular expressions

After implementing this function, I noticed that it is removing the last character of the string. However, the intended functionality was to only replace line breaks with
tags. What could be causing this issue?

    return (str + '').replace(/([^>\r\n]?)(\r\n|\n\r|\r|\n)/g, breakTag);

Answer №1

The initial section of your design identifies any individual character that is not the '>' symbol or a carriage return or line feed, however, it does not append this to the resulting string. Consequently, it consistently removes the final character prior to encountering the line break.

Consider:

return (str + '').replace(/([^>\r\n]?)(\r\n|\n\r|\r|\n)/g, "$1" + breakTag);

Answer №2

why not give this a go

 try using str.replace(/(\r\n|\n|\r)*$/, breakTag)

(I opted for the $ to target the string's conclusion)
