Remove extra spaces in a string in JavaScript
If you want to remove any character from a string, you can use replace method, but if you only want to remove extra spaces that were mistakenly typed and to keep just a single white space between any two words of a sentence, you need to use a regular expression.
const message =
"This is a long message that's carelessly typed with many spaces. ";
message.replace(/\s/gi, '');
// Output → "Thisisalongmessagethat'scarelesslytypedwithmanyspaces."
message.replace(/\s+/gi, ' ');
// Output → "This is a long message that's carelessly typed with many spaces. "Note: There is a space at the end. You can remove it by using the trim method.
message.replace(/\s+/gi, ' ').trim();
// Output → "This is a long message that's carelessly typed with many spaces."If you don't care about the special characters, you can use message.replace(/\W/gi , ' ').trim(). But I won't recommend it.
