• Never use any.
• In case there's no alternative, use unknown (more about unknown).
• Use ReadOnly arrays to ensure there's no scope for mutation (unless mutation is needed).

const numbers: ReadonlyArray<number> = [1, 2, 3];

• Array generics over typecasting.

const numbers: Array<number>;
//instead of const numbers: any[];
