When should I use double or single quotes in JavaScript?

Question

console.log("double"); vs. console.log(\'single\');

I see more and more JavaScript libraries out there using single quotes when ha

Answer 1

One (silly) reason to use single quotes would be that they don't require you to hit the shift key to type them, whereas a double quote do. (I'm assuming that the average string doesn't require escaping, which is a reasonable assumption.) Now, let's suppose every day I code 200 lines of code. Maybe in those 200 lines I have 30 quotes. Maybe typing a double quote takes 0.1 seconds more time than typing a single quote (because I have to hit the shift key). Then on any given day, I waste 3 seconds. If I code in this manner for 200 days a year for 40 years, then I've wasted 6.7 hours of my life. Food for thought.
