将这个对象数组转换为另一个对象的最佳方法是什么？

Question

I have an array of objects like this one:

[
{prop1: valueA, prop2: valueB, prop3: valueC},
{prop1: valueD, prop2: valueE, prop3: valueF},
...
]

I want an array of objects like:

[
{x: valueA, y: valueB},
{x: valueD, y: valueE},
...
]

I want to create a new array of objects using some properties from the old objects, and I also want to change the names of the properties. Is the rest operator a good choice to do it? and which one is the best way to use it? Thanks

A simple Array.map will do this, Are you sure noting more?

 let results = [ {prop1: 'valueA', prop2: 'valueB', prop3: 'valueC'}, {prop1: 'valueD', prop2: 'valueE', prop3: 'valueF'}, ].map(item=>({x:item.prop1, y: item.prop2})); console.log(results);
