FIXING ANTI-PATTERNS IN JAVASCRIPT

Methods, storage systems and computer program products implement embodiments of the present invention that include receiving, by a computer, source code for an application, the source code including multiple instructions to be executed in a single thread. A first static analysis is performed on the application source code in order to identify a given instruction including an asynchronous handler, and a plurality of entry points to the application. Based on the static analysis, an order of execution of the multiple instructions is determined, and an intermediate representation is generated that includes the multiple instructions arranged in the determined order of execution. In some embodiments, a second static analysis can be performed on the intermediate representation that can identify an anti-pattern in the intermediate representation, and then correct the anti-pattern in the source code.
