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.
JavaScript Function bind() With the bind() method, an object can borrow a method from another object. The example below creates 2 objects (person and member).
We use the Bind() method to call a function with the this value, this keyword refers to the same object which is currently selected . In other words, bind() method allows us to easily set which object will be bound by the this keyword when a function or method is invoked.
Apply invokes the function and allows you to pass in arguments as an array. Bind returns a new function, allowing you to pass in a this array and any number of arguments.
In some part of onInit function of a controller in a SAPUI5 application there is an auto generated code like this:
this.getView().addEventDelegate({
onBeforeFirstShow: function() {
// Some codes
}.bind(this)
});
Now my question is what does .bind(this) mean? What does it do? Is it a pure JavaScript code or it is related to SAPUI5?
