Recently the company is engaged in Ibeacon, because the company another learning Android, and the rest of the people, only I touch Java, Android, so I only to do this.Statement, I am a C # programmer, Java, Android are weak, just slightly involved, do not understand, the error, a lot of advice.At first, I search the Internet ibeacon information (using Baidu, alas, it seems I am 2B programmer AH), the most d

First of all, tell me what ibeacon is:IBeacons is the function of the IOS7 system. Use Bluetooth 4.0 (Low power Bluetooth) for data transfer (iphone 4s + devices). Handheld devices can receive signals from Ibecons base stations within a certain range (up to 50m). Any Bluetooth device that implements the Ibeacon protocol can act as a ibeacon base station. Differen

IBeacon is a new function of iOS7. It uses BLE to implement indoor positioning and is accurate to the centimeter level. The test uses two iPhones (BLE supported), one as the iBeacon base station broadcast signal, the Code uses the official source code AirLocate, and the other as the receiving end, directly using the AirLocate downloaded by the App Store ). 1. Main broadcast code NSDictionary * peripheral

Personal Summary: This article on the JS bottom of the working principle is introduced.Original: HTTPS://BLOG.SESSIONSTACK.COM/HOW-DOES-JAVASCRIPT-ACTUALLY-WORK-PART-1-B0BACC073CFOne, engine, runtime, call stackThis is the first chapter of how JavaScript works. This chapter provides an overview of the language engine, runtime, and call stack.In fact, there are a lot of developers who use JavaScript every day in their daily development but don't know t

Personal Summary:1.webassembly Introduction: Webassembly is an efficient, low-level bytecode for developing network applications. Allows languages other than JavaScript (such as C,c++,rust and other) to be used in Web applications to write applications and then compile (early) WebAssembly.This is the sixth chapter of how JavaScript works.Now, we'll dissect how WebAssembly works, and most importantly, its performance with JavaScript: Load time, executi

Personal Summary: It takes 15 minutes to finish this article, this article introduced the abstract syntax tree and JS engine parsing these syntax tree process, referred to lazy parsing-that is, the process of converting to AST is not directly into the function body parsing, when the function body needs to be executed when the corresponding conversion. (because some function bodies are simply declared, and are not actually called)Parsing, Syntax abstraction tree, and 5 tips for minimizing parsing

inheritance works, let's analyze the Inputfield subclasses that inherit from the Component class.class InputField extends Component { constructor(value) { const content = `Here is the output of using Babel to process the above example:var InputField = function (_Component) { _inherits(InputField, _Component); function InputField(value) { _classCallCheck(this, InputField); var content = ‘In this example, the inheritance logic is enca

animation is a collection of ease-in and Ease-out. This is illustrated below:Do not set the animation duration too long, otherwise it will give a feeling that the interface does not respond.Use ease-in-out CSS keywords to implement ease-in-out animations:transition: transform 500ms ease-in-out;Custom easingYou can customize your own easing curve, which allows you to control animations in your project more effectively.In fact ease-in , linear and the ease keyword maps to a predefined Bezier curv
