  45. Execute the string ``code`` as JavaScript code within the browser window. This is a call to the actual global JavaScript function ``eval()``.
    46. 

  46. 

  47. If ``use_global_execution_context`` is ``true``, the code will be evaluated in the global execution context. Otherwise, it is evaluated in the execution context of a function within the engine's runtime environment.
