Explain the different types of JIT in .NET.

JIT compiler is a part of the runtime execution environment that helps in a higher performance by placing the complied code in the cache for a faster execution.

In Microsoft .NET there are three types of JIT compilers:

Pre-JIT :- When an application is being deployed, the Pre-JIT complier compiles the complete source code into a local code in a single compilation cycle.

• Econo-JIT :- Econo-JIT compiles only those methods that are called at runtime.
  However, these compiled methods are removed when they are not required.
• Normal-JIT :- Normal-JIT compiles only those methods that are called at runtime and stored in the cache. This increases speed because subsequent calls to these methods are executed from cache.
