JavaScript Higher-order Functions - 19

JavaScript Higher-order Functions - 19

In this video tutorial, we'll learn JavaScript Higher-order Functions. Basic syntaxes of the function expression. Ways of creating a function pollution. Limitations of arrow functions.

A function expression is another way of creating a function. It makes your code maintainable because each function has its task and it avoids scope pollution - a term used when variables a cluttered within the namespace, thereby making your program more prone to error.

In this tutorial we will learn the function expressions in the following sections:

  1. Basic syntaxes of the function expression
  2. Ways of creating a function pollution
    • Anonymous function
      • Function without function name
      • Self-invoked function
    • Arrow function
  3. Limitations of arrow functions
    • Keywords like this, super, arguments, new.target, and yield can't be used.
    • Can't be used as a constructor.
    • Can't use the syntax of call, apply, and bind methods on arrow functions.

A higher-order function is a function that either takes a function or functions in as an argument or returns a function. All other types of functions are considered first-order functions. Because JavaScript accepts higher-order functions, that is what makes this programming language suitable for functional programming.
