如何使用Ramda通过键值在Array中查找匹配的对象 [英] How to use Ramda to find matching object in Array by key value

问题描述

当前，这给了我 undefined ，但是 R.propEq 应该会在我认为的port中通过键ticker找到匹配的对象?

Currently this is giving me undefined, however R.propEq should find the matching object by key ticker in port I thought?

推荐答案

正如您所说，可以通过将密钥传递给 propEq :

As you say, you can solve it by passing in the key to propEq:

R.find(R.propEq('ticker', 'aa'), port)

另一种选择是使用 eqProps 函数，该函数测试两个对象是否匹配命名密钥:

Another option is to use the eqProps function, which tests if two objects match for the named key:

R.find(R.eqProps('ticker', ticker), port)

您可以看到

You can see the first or second version in the Ramda REPL.
