| Research Abstract |
This research aims to develop an efficient server-side JavaScript engine that is expected to reduce the development cost of web applications. The obtained results can be summarized as follows. (1) We have developed a JavaScript virtual machine that optimizes the program execution on the basis of run-time information. (2) We have developed a foreign function interface that enables the programmer to call C functions from a JavaScript program. (3) We have extended the JavaScript virtual machine described in (1) so that it can run in parallel as event-driven servers. (4) We have developed a gradual type system for a subset of JavaScript programs to be a base of their safe execution.
