Hi, everyone! After a few weeks without writing about JavaScript, it’s about time we talk about it again! This time we’re going to talk about errors and stack traces and how to manipulate them. Sometimes people don’t pay attention to these details but this knowledge will certainly be useful if you’re writing any library related to testing or errors, of course. This week in Chai, for example, we had this great Pull Request which greatly improved the way we handle stack traces in order for our users to have more information when their assertions fail. Manipulating stack traces lets you clean up unuseful data and focus on what matters. Also, when understanding what exactly are Errors and their properties you will feel much more confident taking advantage of it.
