In web pages, the global object is window, so you can set and access global variables using the window.variable syntax.. Consequently, you can access global variables declared in one window or frame from another window or frame by specifying the window or frame name. From now on, I use window to refer to the global object, but in cross-platform code, you should use the preceding pattern and glob instead. The following methods are used to achieve this: Object.create() ... DogObject's prototype is an object (key and value pair), hence it also has a __proto__ property which refers to the global Object protoype. 1. Here is a simple singleton you may use everyday: var user = {name: 'Shruti Kapoor', location: 'SF', intro: function() {return this.name + ', ' + this.location}} Technically speaking, object literals in JavaScript are singletons. The first command require.resolve('fs') displays just 'fs' without any path as it is a default module comes with Node. exports isn't actually a global but rather local to each module. 3. Create an Array. The clearInterval() is used to stop a timer that was set with setInterval(). Exactly one instance of a class is allowed, it is a singleton. (Choose all that apply.)
