• begin(), end()
• All containers

Reversible Container: bidirectional iterators - increment and decrement in O(1)

• rbegin(), rend()

Folder Structure

Please note

While this gist has been shared and followed for years, I regret not giving more background. It was originally a gist for the engineering org I was in, not a "general suggestion" for any React app.

Typically I avoid folders altogether. Heck, I even avoid new files. If I can build an app with one 2000 line file I will. New files and folders are a pain.

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

How to memorise ASCII

You don't need to memorise ASCII as there is a handy chart available by typing man ascii in a Terminal. However, you may find it useful to remember some fun facts about ASCII.

Blocks of 32 are useful. 32 is 2⁵ (2 raised to the power 5) and a block of 32 is enough to represent all 26 common english letters plus some extra stuff.

ASCII is a coding for the first 128 numbers. 0 to 127.
