JScript isn&#x27;t a shorthand for Javascript. It&#x27;s a name for an ill-favored heterodox implementation of ECMAscript. Using it in the fashion you have here will therefore cause knowledgeable engineers to assume you must not know what you&#x27;re talking about. Of course, you&#x27;re welcome to continue doing so nonetheless.<p>Using lambdas in the fashion you describe is a dangerously poor practice that, over the long run, produces code that&#x27;s much harder to maintain than it should be. That&#x27;s why you don&#x27;t see it in environments where changes have to pass peer review by experienced Javascript engineers before being accepted into the codebase. Unfortunately, such environments are far from prevalent and the JS dev world lacks rigor even by comparison with web development as a whole, so you see a lot of people abusing lambdas and encouraging others to do likewise. That doesn&#x27;t make it any less a bad idea.
