Today I discovered that await is more flexible than I thought because it doesn't work only on promises.

In ES6 the static method isNaN was added to the Number prototype. It looks the same behaves slightly different...

I learned about an edge case in 'Array.prototype.indexOf' which is fixed in 'Array.prototype.includes'

I learned how to compare strings in a sane manner using 'String.prototype.localCompare'.

I learned that the IntersectionObserver constructor allows more than one threshold value.
