I am trying to explode an string using javascript to pick searchterms, whitespace-separated. However I get empty array elements if a searchterm is ended by a whitespace, as shown below.

What should I do instead to avoid post-processing this array and removing empty elements?

var str = searchterm1 searchterm2;

console.log(str.split( )); // [searchterm1, searchterm2]



var strb = searchterm1 ; // Note the ending whitespace

console.log(strb.split( )); // [searchterm1, ]
