Why does Crockford say not to use the new keyword if he advises us to use it for prototypal inheritance?

Question

I saw a video in which Crockford told us not to use the new keyword. He said to use Object.create instead if I\'m not mistaken. Why does he tell us not to use

Answer 1

Crockford discusses new and Object.create in this Nov 2008 message to the JSLint.com mailing list. An excerpt:

If you call a constructor function without the new prefix, instead of creating and initializing a new object, you will be damaging the global object. There is no compile time warning and no runtime warning. This is one of the language’s bad parts.

In my practice, I completely avoid use of new.
