Trying out the lodash _.filter to return an array of values that excludes the values in an array. Say I have a collection of objects:
let col = {
data: {
name: "data1",
type: "neighbor"
},
},
{
data: {
name: "data2",
type: "subordinate"
}
},
{
data: {
name: "data3",
type: "affiliate"
}
}
let values = ["neighbor", "affiliate"];
I know I can do something like:
const elementsToKeep = _.filter(col, (v) => _.includes(values, v.data("type")));
which would return "neighbor" and "affiliate" but I want to return "subordinate" instead. I know this should be rather simple but I'm having a hard time figuring it out without writing more extensive logic.
Since the data is not structured properly as @BeerusDev mentioned, let me add the code as the answer and try to explain it.
const col = [{
data: {
name: "data1",
type: "neighbor"
},
},
{
data: {
name: 'data2',
type: 'subordinate'
}
},
{
data: {
name: "data3",
type: "affiliate"
}
}
];
let values = ["neighbor", "affiliate"];
const elementsToKeep = _.filter(col, (v) => !_.includes(values, v.data["type"]));
console.log(elementsToKeep)<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.21/lodash.min.js"></script>Since the result of the _.includes is a boolean value, to get the data which is not inside the array that u have, we need to use !_.includes(...)
