If you can, don't hesitate to ask senior dev for help (but only once you've done your own research). In that case, knowing how to explain what's the problem, in the context of what you are trying to do (the context is important because of the XY problem). Communication with non-dev and person outside your project is important, usually those person will either control the budget or be users and stakeholder. Admit your mistakes, especially when they affect other persons.
