bind(thisArg: Any, argArray: Any*): Dynamic
The bind() method creates a new function that, when called, has its this keyword set to the provided value, with a given sequence of arguments preceding any provided when the new function is called.

def
call(thisArg: Any, argArray: Any*): Dynamic
The call() method calls a function with a given this value and arguments provided individually.
The call() method calls a function with a given this value and arguments provided individually.
You can assign a different this object when calling an existing function. this refers to the current object, the calling object. With call, you can write a method once and then inherit it in another object, without having to rewrite the method for the new object.
apply is very similar to call(), except for the type of arguments it supports. You can use an arguments array instead of a named set of parameters. With apply, you can use an array literal, for example,
fun.apply(this, ['eat', 'bananas'])
or an Array object, for example,
fun.apply(this, new Array('eat', 'bananas')).
MDN
Scala.js-specific note: call() can be used instead of the apply() method available in JavaScript. Simply use the :_* notation to expand a Seq as variadic arguments, e.g.,
someFun.call(thisArg, argSeq: _*)

length is a property of a function object, and indicates how many arguments the function expects, i.e. the number of formal parameters. This number does not include the rest parameter. By contrast, arguments.length is local to a function and provides the number of arguments actually passed to the function.
