V8 also provides various features and optimizations, including:
- Inline Caching: Inline caching is an optimization that remembers the results of property lookups, and method calls on objects. When a property is accessed on an object, V8 caches the lookup result. If the same property is accessed again, the cached result is used, avoiding the need to perform the lookup again. This technique reduces the overhead of repeated property lookups and improves performance.
- Optimization of Hot Code Paths: In most programs, certain sections of code are executed more frequently than others. These sections are known as “hot code paths.” V8 identifies these hot code paths and applies various optimizations to speed up their execution. This might include inlining function calls (replacing a function call with its actual code), loop unrolling (expanding loops to reduce loop overhead), and other transformations that reduce the time spent on frequently executed code.
