r/servicenow on Reddit: Is there a reason not to use ECMAScript 2021 at this point?
March 19, 2024 -
Like the title says - we have a number of scoped apps on our instance and I’m wondering when it makes sense to enable the newer version of JS. From what I can tell, enabling it should have zero negative impacts, as it allows for more capabilities in keywords and objects you can reference, but it doesn’t change the functionality of existing keywords.
With all that in mind, is there a reason why I shouldn’t just enable it across the board on my scoped apps? The main thing that crosses my mind is pseudo tech debt from existing code that would ideally be refactored to use the benefits of ECMAScript

For new apps: no reason. In fact, it's on ECMAScript 2021 by default now for new scoped apps, if that's a good enough vote of confidence for it. For old apps that you are switching to the new version: it's mostly just making sure old code doesn't break: make sure no reserved keywords are variable names, like let, class, const, etc. make sure new scoped variables don't collide with global variables that already exist making sure old code doesn't have object properties/methods that don't uninentionally match any new shorthand syntax rare but if you have octal literals, the prefix changed regex, es6 had new flags so make sure your old regex patterns aren't accidentally triggering them (u for unicode, y for sticky, etc.) new methods and properties for built in objects, make sure your old code aren't already trying to define them (like Number.isNaN came in ES6) a lot of other changes involve strict mode but we don't do that in servicenow so i didn't list them. I made a playlist for SN developers to catch up to es21 if all they know is es5. https://www.youtube.com/playlist?list=PL3rNcyAiDYK1fUOYO83KOfF-NriBRAERV Sorry for the plug, but I thought it was relevant!

Ecma 2021 should be used wherever possible, if not used every piece of new code written into the instance is technical debt
