Javascript Programming Tutorials, Guides & Best Practices

• Use call when you have a fixed number of arguments.
• Use apply when you have an array of arguments or when the number of arguments is unknown.

The bind method creates a new function that, when invoked, has its this value set to the provided value. Unlike call and apply, bind does not immediately invoke the function. Instead, it returns a new function that can be invoked later with the specified this value.
