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

Before using any software, we need to understand how it works, otherwise it will cause a lot of inconvenience to the subsequent use.

The layer-3 switch you know works like this. It works like a layer-3 switch. Why do we say that the L3 forwarding performance of a layer-3 switch is much higher than that of a router? Sometimes it is mentioned in many books that the software of the router is also very powerful and can almost achieve the speed limit forwarding capability. However, it is unlikely that the software can compare with the hardwa

HBase learning Summary (4): How HBase works and how hbase works I. Split and allocate large tables HBase tables are composed of rows and columns. HBase tables may contain billions of rows and millions of columns. The size of each table may reach TB or even PB level. These tables are split into smaller data units and allocated to multiple servers. These smaller data units are called region. The server hosti

reload the data (to be verified)).Ko.computed (function() { var params = { this. PageIndex (), This . Selecteditem.peek () }; $.getjson (this);Note: You can use the extender extension to prevent computed observable from being updated too often.Note: Why circular dependence is meaninglessComputed observable should have a lot of observable input, but only one value output. Therefore, there should be no loops in your dependency chain. Loops and recursion are not the same,
