TypeScript Coding Interview Practice
TypeScript has become the industry standard for large-scale JavaScript applications, and many companies now expect or prefer TypeScript in interviews. It brings type safety to JavaScript without sacrificing the ecosystem or performance, making it ideal for demonstrating software engineering discipline during interviews.
Why TypeScript for Interviews?
TypeScript's static typing helps catch bugs at compile time and makes code more self-documenting — qualities that impress interviewers. It compiles to JavaScript so all JavaScript patterns work, but interfaces, generics, and union types let you express data structures more precisely.

TypeScript Interview Tip
Use TypeScript interfaces to define your data structures upfront — it shows design thinking before writing algorithm code. Generics are useful for linked list and tree node definitions. Don't over-type: use type inference where it's clear.
