Arrow functions are not constructible; just use one of those. On Mon, Apr 24, 2017 at 2:55 PM, J Decker wrote: > function Entity() { > if (this instanceof Entity) throw new Error("Please do not call with new"); > } > > oh the other side; you can bind this to a simple function

Re: Nonconstructors

function Entity() { if (this instanceof Entity) throw new Error("Please do not call with new"); } oh the other side; you can bind this to a simple function call... function f() { } var fWithThis = f.bind( {} /*Something to use as 'this' */ ) call with fWithThis() and f's this will be the

You can use: const foo = { bar() { // Not constructible } }; new foo.bar; //TypeError: foo.bar is not a constructor On Mon, Apr 24, 2017 at 10:42 PM, Raul-Sebastian Mihăilă < raul.miha...@gmail.com> wrote: > I have a dilemma. I like how typically the built-in methods are not >

Nonconstructors

I have a dilemma. I like how typically the built-in methods are not constructors (like Array.prototype.forEach). I have cases in which I'm creating a function in which I want to use `this` but I would like the function to not be constructible. There are ways of doing this: - checking new.target -
