Ask HN: Apply to dev jobs with little experience of the language required?

"Java or C++" is such type of key phrase/statement, but there are other ones, depends on job profile you are looking for. Front end devs should rather avoid job offers, which mention some particular javascript library as an must have requirement.

Question is simple: I don't have a lot of professional experience in required language/technology, but (here goes something interesting about you), should I apply to your job offer?

Indeed. If you've solved a generally applicable problem of computer science, you can leverage that. If you've solved a generally applicable problem of computer science within a tech stack that aligns with the [EDIT: company in question], all the more power to you and the likelihood that they will want to hear what you have to say as an expert on the subject.
