throw Error('msg') vs throw new Error('msg')

Question

var err1 = Error(\'message\');
var err2 = new Error(\'message\');

What\'s the difference? Looking at them in the chrome console, they look identica

Answer 1

Both are fine; this is explicitly stated in the specification:

... Thus the function call Error(…) is equivalent to the object creation expression new Error(…) with the same arguments.
