可以说,我有一个这样的对象数组:

var students = [{
    name: 'Nick',
    achievements: 158,
    points: 14730
}, {
    name: 'Jordan',
    achievements: '175',
    points: '16375'
}, {
    name: 'Ramon',
    achievements: '55',
    points: '2025'
}];

我如何遍历它(如果必须),以便获得某些键值的列表.让我们说一下所有名字的清单.

谢谢.

is there any neat Ramda way of writing something like this:

 const ifOkCompose = (...args) => {
            const r = foo(...args);

            if (r) {
                return compose(bar1, bar2)(r);
            }

            return r;
        };

If foo() returns truthy value, send it to compose, otherwise just return it. There is 'when', but it would return arguments instead of returned value of 'foo(...)'.

In other words, I have a function foo which may return undefined, I use it in compose as compose(bar1, bar2, foo). …
