Types available

06:46 - Some nice ones
just-safe-set → deeply setting dynamic object properties set(data, 'a.long[0].path', value)
object-typeof Why not use typeof? Everything is an object
Why not use array.isArray? Handy to have a switch statement
just-*-case Camel, kebab, snake
just-compare
10:54 - Why?
This is the NPM install of Stack Overflow copy+paste
Handy as hell
Battle-tested Lots of ways to do simple stuff
Sometimes the simple stuff has weird edge cases - these are caught
Sometimes your checks can be messy Check if an object is empty
25 lines
Just install it
12:05 - Other
Great to learn and test yourself
There are tests for each function Run them
See them fail
Try and make it so all the tests pass without looking at the source
