How to combine two value checks into one line in javascript

Question

I have the following code in javascript:

var seasonDropdown = TVContainer.find('select.season').val()
if (seasonDropdown == "-1" || !seasonDropdown) {seasonDropdown = null}

Is there a way to combine these two into one line?

Answer 1

You could do the following:

var seasonDropdown = (TVContainer.find('select.season').val() == "-1" || !TVContainer.find('select.season').val()) ? null : TVContainer.find('select.season').val();

But honestly, you should prefer readability over a solution like this.

if you want a bit cleaner look instead, you could use this:

var seasonDropdown = TVContainer.find('select.season').val();
if (seasonDropdown == "-1" || !seasonDropdown) seasonDropdown = null;
