How to match strings with and without space using regular expression?

I have a regular expression, which matches exact words, if space is in between, it returns false. How can i achieve this? even though I have a space in between or not it has to return true. EX:

var str1 = "This is a fruit";
var str2 = "this is afruit";

str2 = str2.toLowerCase();

if(str2.toLowerCase().match(/a fruit/)){
  alert("matched");
  return true;
} 
return false;

In the above if condition, I have mentioned .match(/a fruit/) it wil return me false because i'm considering space too. I dont want to do like this. Enven if it is "a fruit" or "afruit" it has to return me true. I'm new to regular expression Please help.. I'm stuck here.

Use Below Example

var str1 = "This is a fruit";
var str2 = "this is afruit";

str2 = str2.toLowerCase();
var matchString = 'a fruit';
matchString = matchString.replace(/\s+/g,'');
if(str2.toLowerCase().match(matchString)){
  alert("matched");
  return true;
} 
return false;

var str1 = "This is a fruit";
var str2 = "this is afruit";


str1 = str1.replace(/\s/g, '');
str2 = str2.replace(/\s/g, '');

This will remove white spaces from string. then convert both into lower case and compare as you are.

According to Javascript regular expressions reference:

str2 = str2.toLowerCase();
does_it_match = str2.match(/[a-z ]+/);
if (does_it_match) { return true; }
return false;

/a ?fruit/

or, prettier,

/a\s?fruit/

? means that the previous character is optional. \s is any kind of whitespace.
