javascript - Ramda R.pickBy R.identity 包括 zeros 0

Question

一个简单的问题，我如何通过管道传递 pickBy 身份并包含值为零的 Prop 。目前这个例子会省略零

let linkType = { 
    name: 'zac',
    money: 0,
    problems: 'as much as the money'
}
let linksList = R.pipe(
                    R.pickBy(R.identity),
                  )(linkType);

Answer 1

使用R.either与 R.equal(0)如果值等于 0，则得到 true，以及 R.identity 的结果如果不是:

const linkType = {
  name: 'zac',
  money: 0,
  problems: 'as much as the money',
  another: false
}

const linksList = R.pickBy(R.either(R.equals(0), R.identity))(linkType);

console.log(linksList);
