is there a way in ramda to remove multiple object in ramda.
Here's my array
const availableFeatures = [
{
id: 1,
name: "TEST 1",
},
{
id: 2,
name: "TEST 2",
},
{
id: 3,
name: "TEST 3"
}
]
I want to remove the object that contains id 1 and 2.
I like using where
to build predicates:
const x = reject(where({id: flip(includes)([1, 2])})) console.log(x(availableFeatures));
<script src="https://cdnjs.cloudflare.com/ajax/libs/ramda/0.26.1/ramda.min.js"></script> <script>const {reject, where, flip, includes} = R;</script> <script> const availableFeatures = [ { id: 1 , name: "TEST 1" }, { id: 2 , name: "TEST 2", }, { id: 3 , name: "TEST 3" } ]; </script>
Using R.reject()
with R.propSatisfies()
can allow you to remove all those objects in your array where the object's id
is <=
to 2 like so:
const availableFeatures = [ { id: 1, name: "TEST 1", }, { id: 2, name: "TEST 2", }, { id: 3, name: "TEST 3" } ]; const res = R.reject(R.propSatisfies(R.gte(2), 'id'))(availableFeatures); console.log(res);

You can use reject()
:
const availableFeatures = [ { id: 1, name: "TEST 1", }, { id: 2, name: "TEST 2", }, { id: 3, name: "TEST 3" } ]; const result = R.reject(({id}) => id === 1 || id === 2, availableFeatures); console.log(result);
<script src="https://cdnjs.cloudflare.com/ajax/libs/ramda/0.25.0/ramda.min.js"></script>
You can use this solution
const availableFeatures = [ { id: 1, name: "TEST 1", }, { id: 2, name: "TEST 2", }, { id: 3, name: "TEST 3" } ] const result = R.reject( R.anyPass([ R.propEq('id', 1), R.propEq('id', 2) ]) )(availableFeatures); console.log(result);

also something like this would do:
const blacklist = R.propSatisfies( R.includes(R.__, [1, 2]), 'id', ); const fn = R.reject(blacklist); // ---- const data = [ { id: 1, name: "TEST 1", }, { id: 2, name: "TEST 2", }, { id: 3, name: "TEST 3" } ]; console.log(fn(data));
