Controlling the Time Continuum with Node.js. // functions/index.js /** EXPORT ALL FUNCTIONS * * - Loads all `.function.js` files * - Supports multiple exports from a single `.function.js` file * - It is optimized with `FUNCTION_NAME` env and omiting `node_modules` as well * - Every function from any file must have unique name Counter¶.
The functions below may seem familiar, since they are available in most browsers, but Node.js actually provides its own implementation of these methods. A Counter is a container that keeps track of how many times equivalent values are added. Given an expression that starts with ::, when a digest loop is entered and expression is dirty-checked, store the value as V Counter Up - jQuery Plugin Demo. A function that will handle the event triggered, despite the fact we have three event types, all of them will have the same object properties (as described bellow), where you can access the … The main difference is that the scope of a var variable is the entire enclosing function:

In this way, let works very much like var. If the value of the expression is set within the digest loop and later, within the same digest loop, it is set to undefined, then the expression is not fulfilled and will remain watched. It can be used to implement the same algorithms for which bag or multiset data structures are commonly used in other languages. The Node.js API provides several ways of scheduling code to execute at some point after the present moment. An explanation of why the name "let" was chosen can be found here. Variables declared by let have their scope in the block for which they are defined, as well as in any contained sub-blocks.
