When making a react-based application, I encountered the need to sort the list by drag. When using sortable to add sort support to a list, one problem was found: The data was sorted correctly, but the order of the DOM was messed up, and after a while the reason was found because a dynamic key was specified when rendering the data (map (o,i) = ( from ' Lodash/uniqueid 'When specifying key, adjust:Remember a react drag the pit in the sort: key

easy to understand, but why did the first two return 1? To explain the problem, let's look at the official description:If radix is undefined or 0 (orAbsent), JavaScript assumes the following:A) If the input string begins with"0x" or "0X", radix is hexadecimal and the remainder of the string isParsed.b) If the input string begins with "0″, Radix is eight (octal) or 10(decimal). Exactly which Radix is chosen is implementation-dependent. ECMAScript5 Specifies (decimal) is used, and not all browser

As a mobile-priority framework, Outline has the best response design at the moment, and is one of the best core components of the present. Outline is designed to be an excellent tool that can be used as the basis for your Web project. 4. Startup Launch Li

in the function body is the object that is defined, not the object in which it is used. The downside, however, is that because the arrow function is not named, the stack information gives the tag the anonymous function when debugging. If you use Babel to convert ES6 code into ES5 code, you'll find two interesting phenomena: In some cases, the compiler can determine whether a function name is assigned to a variableThe compiler uses aliases to maintain the contextConst LOADED = () => {This.sets

need to make sure that all JavaScript is done within 8ms of each frame to keep the animation smooth.CSS animations and transformations, on the other hand, run in the main thread and can avoid re-layout/rearrangement if executed efficiently.Given that most animations run during load or user interaction, this can provide a very important space for your Web application to adjust.The Web animations API is an upcoming feature set that can perform high-performance JavaScript animations out of the mai

through the list of all the properties of the original object through Object.keys (), and then iterate through the lists, and if there is a subset, the object is recursively recursive and eventually gets the deep copy of the object: function deepCopy(obj) { let result = {}; let keys = Object.keys(obj), key=null, tem=null; for(var i=0; iIn this way, you get a compatible multidimensional object, and you can implement a deep copy of a special value such as a Function,null,symbol valu

comprehensively, for understanding and the coding, the effort. This is the ranking of async on https://npmjs.org, except Lodash, that's it. Also, Bluebird and Q are all in the top 10, and the basic explanation is that using Process Control components is standard for NODEJS processing callbacks.

make the above example normal output? Look at the following example: Copy Code code as follows: var result = ["1", "2", "3"].map (function (val) { Return parseint (Val, 10); }); Outputs: [1, 2, 3] Console.log (result); 3.map method Compatibility:The map method is not supported in IE8 and the following browsers, and to be compatible with older browsers, you can: a) Don ' t use map -something like Es5-shim to make older IE ' s support. c] Use the method in map _

declarative may look like a "command", but its structure is more like a declarative type. Imperative factorial uses variable values, loop counters, and results to accumulate the computed results. This method explicitly implements a particular algorithm. Unlike declarative versions, this approach has many variable steps that make it harder to understand and more difficult to avoid bugs.

In my development work, I often encounter the need to determine whether a function is a JavaScript native function, sometimes this is a very necessary job. In my development work, I often encounter the need to determine whether a function is a JavaScript native function. Sometimes this is a very necessary job, you need to know whether the function is provided by the browser or encapsulated by a third party and disguised as a native function. Of course, the best way is to evaluate the return valu
