如何获取对象数组并根据属性值创建数组？

Question

I have an array of objects and trying to take thevalues inside those objects and push them into an array based on the same property value. So for example.

array = [
    {name: 'John', age: 12},
    {name: 'Lily', age: 22}
]

I have this array of objects and now I want to iterate through it and create arrays with all name values and age values. The array also needs to be the same name as the values. So the result will be.

name = ['John', 'Lily']

age = [12, 22]

How would I be able to do this?

Answer 1

Just map over the array like so:

 const array = [ {name: 'John', age: 12}, {name: 'Lily', age: 22} ] const name = array.map(e => e.name); const age = array.map(e => e.age); console.log(name); console.log(age);

EDIT

If the array has dynamic objects, you can do this:

 const array = [ {name: 'John', age: 12}, {name: 'Lily', age: 22} ]; for (var key in array[0]) { window[key] = array.map(e => e[key]); } console.log(name); console.log(age);
