setting an Uber property for the sub-object, which points directly to the parent object's prototype property. (Uber is a German word that means "up", "up".) This is equivalent to opening a channel on a child object that can call the parent object's method directly. This line is put here, just to achieve the completeness of inheritance, is purely an alternative nature.V. Copy inheritanceAbove is the use of

Analysis The data set for Uber's drive information, which is open to the public, provides us with a wealth of valuable data sets for transportation, transit times, peak rides, and more. Analyzing this data is not only good for Uber, but it also helps us understand the city's traffic patterns to help us with our urban future planning. This is an article that uses a single sample dataset to analyze the Uber

function'sPrototypeObject. It returnsThis. When I write a method that doesn't need to return a value, I usually have it returnThis. It allows for a cascade-style of programming. Next comesInheritsMethod, which indicates that one class inherits from another. It shoshould be called after both classes are defined, but before the inheriting class's methods are added. Function.method('inherits', function (parent) { var d = {}, p = (this.prototype = new parent()); this.method('

up, basic service can do well.So, I still made a difficult decision, in the future, still less use easy road.PS Tip:In terms of fares, uber-Volkswagen Uber cheap, the most expensive in China, drip-easy road almost. However, easy road comfort car and the official type of the Shenzhou is not much different.Everyday nothing is easy to use road, mainly cars, has opened the city, county-level areas are covered.

You should first think about what problems you are prepared to solve. And whether it's Linux, Android, ARM, C, and so on, I'm here to teach you that every specific technology can not solve the problem alone.S
