"Is the Web Dev job market in a good enough state that I should risk more time and money?" These best people building new software and need help: https://news.ycombinator.com/item?id=18807017 The most in-demand skill is: React. [From using grep/sed excluding JavaScript/JS]. So my answer is: Yes.

Isn't this basically atoi? Which has a lot of edge cases.
pretty much... the main one I tend to ask is the 6 falsy values, clarified as needed. The responses tend to be a good overall indicator of how well the person knows JS.

What's the question? I like to ask them to explain either the concept of closures in javascript, or how `this` works.

What are the values that equate to false in an if statement? false, null, undefined, NaN, "" (empty string), 0 Bonus: An object with a toString() method that returns one of the above won't evaluate directly, but will roughly equal (foo == false). sometimes I'll ask for a function that returns input as a whole number or null, if it's a string, attempt to parse base 10, return null if invalid, return null if the input…
