A computer implemented method and apparatus for translating JAVASCRIPT code across different host environments. The method comprises accessing a document comprising JAVASCRIPT code of a first type; parsing the JAVASCRIPT code of the first type in the document; tracking a location of an event or action in the document in which the JAVASCRIPT code of the first type is present; translating the parsed JAVASCRIPT code of the first type into JAVASCRIPT code of a second type; merging the translated JAVASCRIPT code into a location in a translated JAVASCRIPT file, wherein the location corresponds to the location tracked in the document; and exporting the translated JAVASCRIPT file.
