JavaScript adds a prototype property to that function. A prototype is an object, where it can add new variables and methods to the existing object. i.e., Prototype is a base class for all the objects, and it he

Before jumping into the deep end, you should learn about where Prototype comes from—its purpose, origin, and philosophy. We'll also discuss what differentiates Prototype from other libraries.doi:10.1007/978-1-4302-0502-9_1Andrew Dupont

Node.js is an open-source JavaScript runtime environment that allows developers to execute JavaScript code for server-side scripting and scalable network applications.
Property lookups through the prototype chain When accessing a property in a prototype-based language like JavaScript, a dynamic lookup takes places that involves different layers within the object’s prototypal tree. In JavaScript, every function is an object. When a function is invoked with the...
A brief explanation to what hoisting means in the JavaScript programming languageJavaScript before executing your code parses it, and adds to its own memory every function and variable declarations it finds, and holds them in memory. This is called hoisting....
