How to include whitespaces in string replace?

I need to replace strings like '5 hours' with '5h'. But I'm only able to get it to '5 h'. How to remove the space in between? When I replace the "hours" in my function to " hours" with a whitespace, it replaces nothing and returns '5 hours'.

$('div.block_name span').text(function(){
    return $(this).text().replace("hours","h");
});

Try this:

$('div.block_name span').text(function(){
                    return $(this).text().replace(" hours","h");
                });

This will replace the leading whitespace as well as the string hours with the string h.

You can use regex like so:

// "\s?" means that find a space only if it exists
console.log("5 hours".replace(/\s?hours/, 'h')); // 5h
console.log("5hours".replace(/\s?hours/, 'h')); // 5h
