{Object.keys(employee).map(key => { return (<divkey={key}><h2>{key}: {employee[key]}</h2><hr/></div>); })}</div>); } However, if we are iterating over the values of an object, we cannot safely use the v
The JavaScript for/in statement loops through the properties of an object: Example varperson = {fname:"John", lname:"Doe", age:25}; vartext =""; varx; for(xinperson) { text += person[x]; } Try it yourself » The While Loop ...
浏览器的 Event loop 是在 HTML5 中定义的规范，而 node 中则由 libuv 库实现。同时阅读《深入浅出 nodeJs》一书时发现比较当时 node 机制已有不同，所以本文 node 部分针对为此文发布时版本。浏览器环境 js 执行为单线程（不考虑 web worker），所有代码皆在主线程调用栈完成执行。当主线程任务清空后才会去轮...
Set iterable object to ergodic in the loop. Native iterable object includes Array, String, Set, Map, arguments of function, NodeList and TypedArray. Note: it wouldn't override or break the iterable in the current loop despite the override parameter. Execution and logic controls: #run(): Promi...
Loops are handy, if you want to run the same code over and over again, each time with a different value.Often this is the case when working with arrays:Instead of writing: text += cars[0] + "<br>"; text += cars[1] + "<br>"; text += cars[2] + "<br>"; text += ...

An alternative approach is to use theArray.forEach()method to iterate over the object's keys and push JSX elements into an array which we then render. App.js exportdefaultfunctionApp(){constemployee={id:1,name:'Bob',salary:123,};constresults=[];Object.keys(employee).forEach(key=>{resul...
In this section, we explain how JS-son agents make use of the BDI (and plan) concepts and how the Environment object type processes agent actions. For detailed documentation of the corresponding JS-son object types and functions, generate the JSDoc (see below).Agent:...
