How to use typeof and switch cases in Javascript

Question

I'm having problems finding out what's wrong with the code below. I have consulted how to use typeof and switch cases, but I'm lost at this point. Thanks in advance for your advices.

// Write a function that uses switch statements on the // type of value. If it is a string, return 'str'. If it // is a number, return 'num'. If it is an object, return // 'obj'. If it is anything else, return 'other'. function detectType(value) {   switch (typeof value) {     case string:       return "str";     case number:       return "num";     default:       return "other";   } } 

------------- Update -----------------------------------

Turns out the problem comes from my mistake (or rather oversight) of not following the instructions properly. Thanks again for your help and comments!

Answer 1

typeof returns a string, so it should be

function detectType(value) {   switch (typeof value) {     case 'string':       return "str";     case 'number':       return "num";     default:       return "other";   } }
