Software Development Terms Beginning with F

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";
}
