 ## Optimized libraries
 
-While the best performing code in Luau spends most of the time in the interpreter, performance of the standard library functions is critical to some applications. In addition to specializing many small and simple functions using the builtin call mechanism, we spend extra care on optimizing all library functions and providing additional functions beyond the Lua standard library that help achieve good performance with idiomatic code. For example, functions like `insert`, `remove` and `move` from the standard library have been tuned for performance on array-like tables, achieving 3x and more performance compared to un-tuned versions, and Luau provides functions like `table.create` and `table.find` to achieve further speedup when applicable.

We also use a carefully tuned dynamic string buffer implementation for internal `string` library to reduce garbage created during string manipulation.
