There are reasons for using array literal notation over class instantiation notation. Afaiui, it's due to the ability to override the "Array" constructor,...

Yes there is a workaround, one that still respect JSLint guidelines You can fix the length without the array constructor, even with a dynamic value Just do: ...
According to MDN that is not what actually happens: https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/Array/length You can only...
When experimenting with the developer console in Chrome and FireBug in FireFox, the effects of the two methods appear to be *exactly* the same. While setting...
... The MDN documentation is unfortunately not very clear on this page. It says that "the array still contain only 2 elements". It's true, as when you do "new...
... new Array is deeply confusing to people coming to JavaScript from other languages because JavaScript's arrays do not work as expected. Much of that...
... If I want to create, say, a separator line of 'len' dashes, I can do that really cleanly and easily with: var separator = Array(len).join('-'); If there's...
... Wouldn't it be clearer and more maintainable to create a function for it anyway? var seperator = repeatString('-', len); it doesn't look as "clever" to use...
... I think that it's more maintainable and more secure to use a dedicated function One going to the code using the Array constructor might expect that the...
... Right. So I personally find that taking advantage of what the language has to offer helps me do that. If I have to write a function, document it, and write...

You may not code for "noobs", but you will have new hires, and you will document that one-liner or have to explain it, even to professionals... Knowing how to...

Please, you assume much Is it creating a new array of length 'len' and joining it to the string literal '-' ? -- and JSLint is supposed to make code clearer......
One of the problems I have with this discussion is that the cost of having to go read this repeatString() function, however it is implemented, is significant....
i just think JSLint isn't for everyone. i had been using it with greater or lesser enthusiasm for years until, after watching the video of douglas' talk at...
