Compilation the closure of TypeScript nested function into Common Intermediate Language of .NET platform

Abstract

This article proposes a method that allows you efficiently compile the closure of nested functions with captured variables into the Common Intermediate Language of the .NET platform. The considered method is based on the idea of ​​transforming the intermediate representation of the program by creating a structure that stores the values ​​of closed variables and passes them to the last argument in the nested function. This allows you to associate a function call with its captured variables. CIL instructions are generated for the converted program. The result of the method is the generated code, which shows better performance than the code generated by the existing analog.
