Practice Javascript by writing implementations for Lodash functions.

Lodash is a popular Javascript library that has many small utilities. I thought it'd be fun to practice by reimplementing them with a test suite.

To make this repo, I pulled out a few interesting functions from Lodash, cleaned up the tests, and removed the body of the function. In some cases I also simplified the functions to keep the focus on the core purpose of the function.

Install the deps (just a testing tool)

yarn install

1. Run the tests yarn test-all
   It will break on the first failure so you're not confronted with a wall of red text.
2. Implement the first function in 01-negate.js
   The comment above the function describes the arguments and gives an example.
3. Rerun the tests and check if it works!

These are ordered roughly in order of increasing complexity.

• negate
• once
• curry
• memoize
• throttle
• debounce
