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
