What will be an ideal response?
Functions are generally treated as blocks of code that execute a series of tasks or return a calculated value. However, almost everything in JavaScript is an object and functions are no different. The fact that functions are objects means that whatever can be done with a regular object can also be done with a function. Some of the unique things that can be done with a function in JavaScript are as follows:?• Storing a function as a variable• Storing a function as an object property• Using one function as a parameter in another function• Nesting one function within another function• Returning a function as the result of another function• Modifying the properties of a function?Because functions are objects, there are several ways of creating and saving the functions used in a JavaScript program.
