Take the one for example, here's how you flatten a two-dimensional array: const nestedArray = [['👍', '🐍'], ['👎', '🐘'], ['👏', '➡']]; const flatArray = [].concat(...nestedArray); console.log(flatArray) // [ '👍', '🐍', '👎', '🐘', '👏',...
You can also use the Array constructor to create an array. You canArray()constructor to create an array with the length of the incoming value; you can also pass the elements to be saved to the Array constructor to create an array containing the incoming value. // 传入要保存的元素 const ...
