Answer 1

First, you have spelling error:

You should do:

var str = ' abc';
str = str.replace(/ /g,"");

The /g is global modifier which will replace the specified text throughout the given string.

Alternatively, you can use split and join like this:

var str = ' abc';
str = str.split(" ").join("");
