const _ = require('lodash'); const nestedObject = { a: 1, b: { c: 2, d: { e: 3 } } }; const flattenedObject = _.flattenDeep(nestedObject); console.log(flattenedObject); // 输出: [1, 2, 3] 使用ES6 JavaScript展平嵌套对象 ...
将嵌套的JavaScript对象转换为平面数组可以通过递归遍历对象的属性来实现。下面是一个示例代码: 代码语言:javascript 复制 functionflattenObject(obj){letresult={};functionrecurse(cur,prop){if(Object(cur)!==cur){result[prop]=cur;}elseif(Array.isArray(cur)){for(leti=0,l=cur.length;i<l;i++){re...
flatten(original, options) Flattens the object - it'll return an object one level deep, regardless of how nested the original object was: import{flatten}from'flat'flatten({key1:{keyA:'valueI'},key2:{keyB:'valueII'},key3:{a:{b:{c:2}}})// {// 'key1.keyA': 'valueI',// ...
flatten nested arrays flatten(a[i], shallow, r); } else { // If the current element is not an array, push it to the result array r.push(a[i]); } } // Return the flattened array return r; } // Output the result of the flatten function with a nested array console.log(flatten...
getPrototypeOf(obj)); const propNames = Object.getOwnPropertyNames(obj); propNames.forEach((name) => { const desc = Object.getOwnPropertyDescriptor(obj, name); Object.defineProperty(copy, name, desc); }); return copy; }; const obj1 = { a: 1, b: 2 }; const obj2 = copy(obj1); ...
const nestedList = [133, 235, 515, [513, 15]];const flattenList = nestedList.flat();console.log(flattenList) // [133, 235, 515, 513, 15] 1. 就像这样,咱们的id 数组被扁平了。 使用object .freeze 避免对象被改变 随着函数式x编程的兴起,数据不可变也越来越重要,咱们可以使用Object.freeze ...

Inside getUser function we return aJusttype object. Then from propPath, we getJust Justtype object. That's why we need flatten it. The way to solve the problem is using flat map which is called 'chain' in Crocks. getUser(1)
