Use pronounceable variable names

If you can’t pronounce it, you can’t discuss it without sounding like an idiot.

Bad:

type DtaRcrd102 = {
  genymdhms: Date;
  modymdhms: Date;
  pszqint: number;
};

Good:

type Customer = {
  generationTimestamp: Date;
  modificationTimestamp: Date;
  recordId: number;
};
