Quickly generate arrays using Array.from

Usually we generate a regular array using a circular insertion method, such as using a time selection plug-in, we may need to store the hours in the array:

let hours = [];for (let i = 0; i

< 24; i++) { hours.push(i + '时');} 如果使用 Array.from 我们可以简写为: let hours = Array.from({ length: 24 }, (value, index) =>

index + 'time'); Thank you for reading!
