How to use Ramda to find matching object in Array by key value

rated 0 times [ 177] [ 7] / answers: 1 / hits: 18596 / 8 Years ago, tue, december 27, 2016, 12:00:00

var portfolio = [{ticker: aa},  {ticker: bb}];



var ticker = {ticker:aa};



var exist = R.find(R.propEq('ticker', ticker), portfolio)



console.log(exist)

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

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

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

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)

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