在JavaScript 中,ES2019 引入了 Array.prototype.flat() 方法来扁平化数组。 depth: number, 可选 指定要提取嵌套数组结构的深度。默认为 1。如果深度大于数组的最大嵌套深度,所有嵌套的数组都会被扁平化为一个数组。如果设置为 Infinity,则会完全扁平化数组。 示例: const nestedArray = [1, [2, [3, [4]...
It was always complicated to flatten an array in #JavaScript. Not anymore! ES2019 introduced a new method that flattens arrays. And there's a "depth" parameter, so you can pass in ANY levels of nesting. AMAZING 🤩 constnested=[['📦','📦'],['📦']];constflattened=nested.flat(...
How do you flatten array in javascript If you are given an array that contains literals, arrays and objects and you want to get all the values to one array. Here is the snippet using recursive function to attain that. functionimplode(arr){varres = [];for(vari =0; i < arr.length ;...
