var str=" I have outer spaces ";
var cleanStr=str.trim();//trim() returns string with outer spaces removed

const removeSpaces = str => str.replace(/\s/g, '');

// Example
removeSpaces('hel lo wor ld');      // 'helloworld'

 var str = "       Hello World!        ";
alert(str.trim());
 

value = value.trim();

var str = "       Hello World!        ";
alert(str.trim());

yourvariable.trim()

var str = '/var/www/site/Brand new document.docx';

document.write( str.replace(/\s/g, '') );

/*
For browsers that do not support the trim() method, 
you can remove whitespaces from both sides of a string with a regular expression:
*/
 function myTrim(x) {
  return x.replace(/^\s+|\s+$/gm,'');
}


 function myFunction() {
  var str = myTrim("        Hello World!        ");
  alert(str);
