Type Inference

TypeScript is great at type inference. Instead of explicitly declaring the type of every variable, TypeScript can infer it from the value:

// explicit (unnecessary)
const bootupLog: string = "starting server...";

// inferred (preferred)
const bootupLog = "starting server...";

Both are equally type-safe, but the inferred version is less typing and leaves less room for human error. Let TypeScript infer types for you!
