Map [1]

Operation	Time Complexity
Access	O(log n)
Search	O(log n)
Insertion	O(n) for <= 32 elements, O(log n) for > 32 elements [2]
Deletion	O(n) for <= 32 elements, O(log n) for > 32 elements

TS-JEST & JEST-EXTENDED SUPPORT

This gist is designed to explain how to configure a project where you have your test code separated from your codebase. The project file structure looks a bit like this:

project
├─┬ lib                    # could be src
│ ├── globals.d.ts         # source code specific type declarations
│ └── index.ts
├─┬ tests

ZSH CheatSheet

This is a cheat sheet for how to perform various actions to ZSH, which can be tricky to find on the web as the syntax is not intuitive and it is generally not very well-documented.

Strings

Description	Syntax
Get the length of a string	${#VARNAME}
Get a single character	${VARNAME[index]}

HoC (pattern) vs Render Props (pattern) vs Hooks (not pattern, a new API)

Someone was asking me about comparing the HoC and Render Props patterns (and their shortcomings) to hooks. I might leave this up as a public gist for others if it's helpful.

Issues with HoC:
