Different Ways Of Function Declaration In Javascript Pdf The function keyword can be used to define a function inside an expression. you can also define functions using the function declaration or the arrow syntax.

In short, use function declarations when you want to create a function on the global scope and make it available throughout your code. use function expressions to limit where the function is available, keep your global scope light, and maintain clean syntax. In javascript, there are two primary ways to define functions: function declarations and function expressions. while they may seem similar at first, they have some key differences. Use declarations if we want our functions to be available everywhere in the file and don't want to worry about the order in which we write them. use expressions if we want to be more strict. When javascript prepares to run the script, it first looks for global function declarations in it and creates the functions. we can think of it as an “initialization stage”.
