I'm trying to filter an array and remove the entries that contain certain properties. For example, my array looks like this:
const items = [{a: "apple", b: "banana", c: "coconut"}, {a: "apple"}, {b: "banana, c: "coconut"}];
And I want to filter out the items that have the properties b or c.
Right now I have:
items.filter(item => "b" in item || "c" in item);
but I feel like there is a better way to do this, and set it up so a lot more properties could easily be added in the future.
Put the property names in an array, and use .some() to test if any of those properties exists.
const items = [{
a: "apple",
b: "banana",
c: "coconut"
}, {
a: "apple"
}, {
b: "banana",
c: "coconut"
}];
let properties_to_filter = ["b", "c"]
let result = items.filter(item => properties_to_filter.some(prop => prop in item));
console.log(result); const items = [{a: "apple", b: "banana", c: "coconut"}, {a: "apple"}, {b: "banana", c: "coconut"}]
let filtredKey = ["a"]
let result = []
items.map(el => {
if(el.hasOwnProperty("c"))
result.push(el)
})
console.log(result)
