Is there a way to determine if a string is empty, even if it contains hard returns?

I am currently working on a function that checks if a string is empty or not, but it seems to be missing the detection of new lines.

export const isStrEmpty = function(text: string): boolean {
  return !text || text.match(/^ *$/) !== null;
};

I attempted to include \n, but it did not have the desired effect.

export const isStrEmpty = function(text: string): boolean {
  return !text || text.match(/^ *\n$/) !== null;
};

Is there a way I can modify this function to properly detect new lines within the string?

Answer №1

For those looking to utilize regular expressions:

^\s*$

In this expression, \s* will match any whitespace character (such as [\r \n \t \f \v])

You can find a similar inquiry discussed here: How to determine if a line is empty using regex

Answer №2

check if the letter is empty and return true or false accordingly.

Give this a shot.
