In today’s tutorial, we will show you simple solutions for removing spaces from a string and explain each step.
Here \s is the regex for whitespace, and g is short for the global flag, which means match all \s (whitespaces). Each contiguous string of space characters is replaced with the empty string because of “+”.
You can also use another version:
You can add content between the single quotes whatever you want to replace whitespace with any string. For example if you type '#', you will grap the difference:
The split() and join() methods can also be used to delete the space from the given string:
You can use any of these two fast methods, however, take into account the following facts:
The replace() method executes a search for a match in a string, and replaces the matched substring with a replacement substring. The pattern can be either a string or a regex. The replacement can be either a string or a function to be called for each match. If the pattern is a string, only the first occurrence will be replaced.
The split() method cuts a string into an ordered set of substrings, puts them into an array, and returns it. The division is achieved by searching for a pattern, which is provided as the first parameter in the method's call. To reverse the split, call join(). which will create an array items string along with glue between them.
