What are the optimization techniques of V8 engine?

V8 engine uses the below optimization techniques.

1. Inline expansion: It is a compiler optimization by replacing the function calls with the corresponding function blocks.
2. Copy elision: This is a compiler optimization method to prevent expensive extra objects from being duplicated or copied.
3. Inline caching: It is a runtime optimization technique where it caches the execution of older tasks those can be lookup while executing the same task in the future.
