How to dynamically remove extra space in a string in Javascript?

Question

How can I make extra space be removed in a string in Javascript ?

For example

I have a string the following string

var string ="how    are you today";

I would like to know what function or trick I could use to dynamically remove extra space in strings in Javascript so that I can have var string ="how are you today"; instead ..

How could I do this ?

I know it's just an example but even for an example you shouldn't use a variable name like string. — Robin van Baalen

Lets assume you have var myString ="how are you today";

If you just want to handle spaces:

myString.replace(/ +/g, ' ');

If you want to replace tabs and new lines as well:

myString.replace(/\s+/g, ' ');

Please note that this does not change the value of myString, but rather return a new string with the spaces removed. So to save this result you would do, for example:

var fixedString = myString.replace(/ +/g, ' ');
