03:44 - What is Just?

https://github.com/angus-c/just
No dependencies
It’s written in JS, so you can copy+paste them if you really need it
Types available
https://medium.com/@angustweets/just-a12d54221f65#.ljib0mfr5

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
