I list two examples and if you decide to apply I expect you to choose one and send me an example.
What is IIFE (Immediately Invoked Function Expression), and how it can be useful?
An IIFE (Immediately Invoked Function Expression) is a method to immediately execute a function as soon as it is created. Moreover, they do not over-populate global objects and hence, is a simple solution to isolate variable declarations.
What is the difference between Call, Apply and Bind?
Call() method invokes the function with this value and arguments provided whereas, apply() invoke a function and allows users to pass arguments as an array, however, bind() accepts arrays or any number of arguments to return a new function. Moreover, apply() accepts arrays as arguments, whereas call() accepts a comma-separated list as arguments.
What is a first class function?
First-class functions are functions that behave and function like variables in a programming language, i.e., they can be passed to other functions as arguments and can be returned by other functions to use the result as a value that needs to be assigned to a variable.
