基于ES6 Array.of的用法(实例讲解)

const arr1 = new Array()
const arr2 = new Array(5)
const arr3 = new Array(1, 3, '白色', {p1: 'v1'})
console.log('%s', JSON.stringify(arr1))
console.log('%s', JSON.stringify(arr2))
console.log('%s', JSON.stringify(arr3))

[]
[null,null,null,null,null]
[1,3,"白色",{"p1":"v1"}]

const arr4 = Array.of()
const arr5 = Array.of(5)
const arr6 = Array.of(1, 3, '白色', {p1: 'v1'})
console.log('%s', JSON.stringify(arr4))
console.log('%s', JSON.stringify(arr5))
console.log('%s', JSON.stringify(arr6))

[]
[5]
[1,3,"白色",{"p1":"v1"}]
