Discussion on: Javascript Shorthand Coding Techniques

[Pacharapol Withayasakpunt]

12 and 15 is well-known to be quite dangerous, that is why rather than

let c = a || b  // All falsy value is short circuited.

This is safer

let c = a ?? b  // Does not short circuit '', 0, NaN; only null and undefined

Without ??, I do have to write my own utility function sometimes.
