Describe your feature request here.

How can I catch console.assert condition failure in Python?

Hi, if you run the following minimal example it will print the assertion failure to the console:

import pythonmonkey as pm pm.eval('console.assert(false)') Assertion failed

This makes it difficult to catch/handle on Python side, when only printed to the console.

If you look at the specs for assert: https://developer.mozilla.org/en-US/docs/Web/API/console/assert_static printing to the console is all the assert method does

Perhaps you mean to use console.trace? https://developer.mozilla.org/en-US/docs/Web/API/console/trace_static That should print according to specs as well...

Please see https://github.com/Distributive-Network/PythonMonkey/pull/360 for a yet-unreleased fix to console.trace
