Javascript object forEach howto?

  • How to loop through a plain JavaScript object with the objects as members? 17 answers

    • What you have here is a JavaScript question, not a TypeScript question. TS and JS have the same runtime semantics.

    forEach is a method of Array . Objects don't have forEach . The semantics of forEach don't make sense on regular objects -- your obj doesn't have a length or a 0 property, for example, which are the kinds of things forEach looks for.
