Assiging a method to a variable in Javascript

Question

Answer 1

You can use .bind() to bind the object to the method call. For example, if you're trying to save a method of a specific object into myFunc, then you can do this:

myFunc = myClass.foo.bind(myClass);

Then, when you later do:

myFunc(...);

it will actually use the object reference myClass to call it properly as a method.

See the MDN reference on .bind() for more details.
