Factory Function in JavaScript
Section titled “Factory Function in JavaScript”A factory function is a regular function that uses the return keyword to produce a new object whenever you invoke it with a different argument.
In other words, a factory function serves as a template for producing new JavaScript objects.
Here’s an example:
// Define a factor function:function createName(name) { return { name };}
// Create an object from the createName() factory:const bestWebsite = createName("CodeSweetly");
// Create another object from the createName() factory:const author = createName("Oluwatobi");
// Create a third object from the createName() factory:const sweetColor = createName("Pink");
// Check bestWebsite's content:bestWebsite;
// The invocation above will return:{ name: "CodeSweetly";}
// Check author's content:author;
// The invocation above will return:{ name: "Oluwatobi";}
// Check sweetColor's content:sweetColor;
// The invocation above will return:{ name: "Pink";}The createName() function is a factory function because:
- It uses the
returnkeyword to produce its object. - It creates a new object whenever you invoke it with a different argument.
