How to Find Similar Objects in an Array Using JavaScript ES6?

You can find similar objects in an array using JavaScript ES6 by creating a comparison function that checks if the properties of two objects are equal. Then, you can use the filter() method to find all objects in the array that match the comparison function.

For example, consider the following array of objects:

const fruits = [
  { name: "apple", color: "red" },
  { name: "banana", color: "yellow" },
  { name: "grape", color: "purple" },
  { name: "apple", color: "green" }
];

To find all objects in the array that have the name “apple”, you can use the following code:

const similarFruits = fruits.filter(fruit => fruit.name === "apple");
console.log(similarFruits);
// Output: [{ name: "apple", color: "red" }, { name: "apple", color: "green" }]

This code creates a comparison function using an arrow function, which returns true if the name property of the fruit object is equal to “apple”. The filter() method then returns a new array containing all objects in the fruits array that match the comparison function.

You can modify the comparison function to check for similarity based on any properties of the objects in the array.
