javascript remove duplicate objects from array
Here are some ways to remove duplicate objects from an array in JavaScript:
Method 1: Using the filter() method
Method 2: Using the Set() method
Method 3: Using the findIndex() method
Method 1: Using the filter() method
The filter() method creates a new array of elements that pass the conditional we provide. To remove duplicates from an array of objects, we can use the filter() method to filter out elements that are not the first in the array to have that property value.
Method 2: Using the Set() method
A Set is a collection of unique values. To remove duplicates from an array, we can first convert the array to a Set. The new Set will implicitly remove duplicate elements. Then, we can convert the set back to an array.
Method 3: Using the findIndex() method
The findIndex() method returns the index of the first element in the array that meets the specified condition. To remove duplicates from an array of objects, we can use the findIndex() method to check if each object is repeated in the array. The new array won't contain any duplicate objects.
