Going too far with Jest Custom Matchers in TypeScript
Going too far with Jest Custom Matchers in TypeScriptDear future me, and other people who land here trying to copy-paste a matcher. Hereâ€™s the gist for you. I needed a Jest custom matcher a few days ago, and I couldnâ€™t find any article I could copy-paste it from.

Your Jest Tests are Leaking Memory
Jest is designed in a way that makes memory leaks likely if youâ€™re not actively trying to squash them.
