I want to filter this array of Object:
const testArray = [{
id: 4,
filters: ["Norway", "Sweden"]
}, {
id: 2,
filters :["Norway", "Sweden"]
}, {
id: 3,
filters:["Denmark", "Sweden"]
}]
with the filter
const myFilter=["Norway", "Sweden"]
However my code just returns []? What I have tried so far:
const testArray = [{
id: 4,
filters: ["Norway", "Sweden"]
}, {
id: 2,
filters :["Norway", "Sweden"]
}, {
id: 3,
filters:["Denmark", "Sweden"]
}]
const myFilter=["Norway", "Sweden"]
console.log(testArray.filter(e=>e.filters===myFilter))
You can use Array#every to test the equality+ of two arrays as follows:
const output = testArray.filter(
e => e.filters.every(
filter => myFilter.includes(filter)
)
);
const
testArray = [{ id: 4, filters: ["Norway", "Sweden"] }, { id: 2, filters :["Norway", "Sweden"] }, { id: 3, filters:["Denmark", "Sweden"] }],
myFilter = ["Norway", "Sweden"],
output = testArray.filter(
e => e.filters.every(
filter => myFilter.includes(filter)
)
);
console.log(output)NOTE: Array#every as used here just confirms that every element of each array is in the other, regardless of the order in which the elements appear.
