I find this comes up a lot, particularly when you're doing code generation stuff, because you need to have examples of code for the LLM, and that code often has strings embedded inside it. For example, take a look at the code properties in this JSON array[1].

Introducing stringify.org, the world's only correct-by-definition JavaScript string encoder website. It uses JSON.stringify, which is the only guaranteed method to output a string that is also valid JavaScript. It's in the spec.
