反转数组时属性未在 Angular 组件中更新

Question

I have an Angular Component which has a public array variable initialized to [] . In the constructor I am getting a response from a service and updating the array using this.variable = array.reverse() . But this doesn't store the reversed array rather the original one. Anything I am missing. Thanks in advance.

Answer 1

You need to change the reference to the array, so try

this.variable = [...array].reverse()

Answer 2

you have missed () to reverse() method try this.variable = array.reverse()
