Javascript - How to remove all extra spacing between words

Question

How can I remove all extra space between words in a string literal?

\"some    value\"

Should become

\"some value\"
<         


        

Answer 1

In case we want to avoid the replace function with regex,

We can achieve same result by

str.split(' ').filter(s => s).join(' ')
// var str = "    This    should  become   something          else   too . ";
// result is "This should become something else too ."

First, split the original string with space, then we will have empty string and words in an array. Second, filter to remain only words, then join all words with a whitespace.
