JavaScript remove leading and trailing spaces [duplicate]

Question

Here is a test:

console.log(" Golden Katana of the Unflinching Dawn                                    ".replace(/\s+/g,""))

I want to remove the extra spaces at the end of the string but it removes every space in the string, so how could I remove just the extra spaces at the end and just keep Golden Katana of the Unflinching Dawn?

Answer 1

You can use str.trim() for this case. It removes the leading and trailing whitespace from a string. The regular expression str.replace(/^\s+|\s+$/g,'') will alternatively do the same thing.
