JS, method behind the madness.

Daniel Dennis on September 08, 2020

Hi There, Welcome to my first Post ☄ It all started with this meme A friend of mine called me out as a now lover of JS. To be honest, ...

I think your example code is a bit off

 const array = [6,-2,2,-7]; array.sort((a,b)=>{ a-b; });

The arrow function you've supplied here always returns undefined.

I think you intended to write this instead:

 const array = [6,-2,2,-7]; array.sort((a, b) => a - b);

The moral of this story is to always test your examples. :)

Same with that one ;) (missing the return):

const array = [6,-2,2,-7]; array.sort(function(a,b){ a-b; });

to work it should be:

const array = [6,-2,2,-7]; array.sort(function(a,b){ return a-b; });

Ah JavaScript. A jungle of landmines. There’s even a pitfall when it’s used for sorting numbers.

Billy Okeyo • Sep 8 '20

Some good insights on that. I love your conclusion

Thanks for the article! JS has some weird gotchyas and it's nice to be reminded of specific examples.
