To be fair ubiquitous and popular aren't necessarily the same! ;-) Anyway, webstorm is an excellent IDE for JavaScript (and though not free it's pretty cheap). I've not used it but I believe IntelliJ (also from Jetbrains) contains the same functionality which might be relevant if you're from a Java background and want to use a single IDE.

OK maybe I need to clarify... I meant "growing in popularity" more in the context of development outwith the browser/DOM. I.e., it gets used where other alternatives are available. By "function's entry point" I meant locating the point in the code at which a function is invoked. Parameter properties: there is no way for an IDE to know the properties of a given object before runtime! Anonymous functions: I may not like them, but others whose code I need to maintain do. JSLint does not know whether I have mistyped a property name of a given object, for instance.

@funkybro "there is no way for an IDE to know the properties of a given object before runtime" There is, just include "whateverMyObjectIs.js" as a referenced script in the ide, and for mistyped property names, try webstorm it does this (if I remember correctly).

There is not! Consider this code: var myFunc = function(param) { ... }; var myObj1 = { fooProp: fooVal, barProp: barVal}; var myObj2 = { catProp: catVal, dogProp: dogVal}; myFunc(myObj1); myFunc(myObj2); How can an IDE offer code completion on myFunc's param parameter? param could be any object of any type, with any properties.

Yes, but presumably the params you're passing in are actually available in that context. A parser can sort that out without being its own full blown JS interpreter.
