ACCELERATED PARSING IN A VIRTUAL MACHINE FOR SIMILAR JAVASCRIPT CODES IN WEBPAGES

摘要

A method and computing device for generating an intermediate representation of received source code for compiling or interpreting on the computing device are disclosed. The method may include receiving source code at the computing device and finding similar source code cached on the computing device that is not the same as the received source code. The received source code is compared to the similar source code to determine one or more differences between the received source code and the similar source code. Metadata for the similar source code is accessed, an intermediate representation of the cached source code is retrieved, and the intermediate representation of the cached source code is first copied and the copy is modified using the one or more differences in connection with the metadata to generate an intermediate representation for the received source code.
