design pattern<\/a> involves creating a new object by copying an existing object rather than creating it from scratch.<\/p>\n\nThe prototype pattern<\/strong> is useful when the creation of new objects<\/strong> is expensive<\/strong> or when the creation process<\/strong> is complex<\/strong> and requires many resources<\/strong>. By using an existing object as a prototype<\/strong>, we can avoid the expensive creation process and simply clone the prototype to create a new object.<\/p>\n
