How can I check for an empty/undefined/null string in JavaScript?

Question

I saw this question, but I didn\'t see a JavaScript specific example. Is there a simple string.Empty available in JavaScript, or is it just a case of checking f

Answer 1

You can use lodash: _.isEmpty(value).

It covers a lot of cases like {}, '', null, undefined, etc.

But it always returns true for Number type of JavaScript primitive data types like _.isEmpty(10) or _.isEmpty(Number.MAX_VALUE) both returns true.
