Profiling in production

React DOM automatically supports profiling in development mode for v16.5+, but since profiling adds some small additional overhead it is opt-in for production mode. This gist explains how to opt-in.

Coding Challenge: Waterfall Analysis

When a startup closes a new financing round (called a Series A, B, C, and so on), a new share class with preferred rights is usually created. These protect new investors in case the company gets sold at a lower valuation than the current financing round (while founders and employees might still get a pretty nice return). They are called liquidation preferences. When the company is sold (called an “exit”), the money of the exit has to be divided among all shareholders according to these liquidation preferences.

The basic rules are:

1× non-participating

The investor gets paid back 1× their originally invested amount, nothing else. The rest is divided among all the other shareholders according to their ownership in the company (this is called “pro-rata”).
