Ramda R.pickBy R.identity 包括零

Question

简单的问题，我如何通过管道传递 pickBy 身份并包含值为零的道具。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

如果没有则使用R.either with R.equal(0) to get true if value equals 0, and the result of R.identity：

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);
