why “Single-quoted string preferred over double-quoted string.” in js?

Question

While using gjslint, I got a hint: \"Single-quoted string preferred over double-quoted string\".

So why? I\'m a little confused with this. Why single-quoted preferred?

Answer 1

If you use single quotes, you do not have to escape the double quotes in your html.

For example...

With single quotes you can do this

var a = 'a link/a>';

with double quotes you would need to escape those inside double quotes, like so

var a = "a link/a>";

Much more work, more difficult to maintain, and easier to commit errors.
