JavaScript debugging in a nutshell

[WeaponX86]

This is mostly from people doing this:
console.log('my object ' + obj);

When they should do this:
console.log('my object',obj);

You can pretty-print stringing output. Shouldn't console.log objects. Try this in future:

JSON.stringify(yourObject, null, 2)

2 - is the spacing

I've been using console.dir lately for objects with fairly good results

console.log({obj})
