find() method

In JavaScript, find methods is used to search for elements in an array based on a given condition.

KeyPoints:

1. The find method returns the value of the first element in the array that satisfies the provided testing function.

2. It returns the first element that matches the condition. If no elements match, it returns undefined.

Example:

1. Filtering Even Numbers:

const numbers = [1, 2, 3, 4, 5, 6, 7, 8, 10];
const data = numbers.find(num => num % 2 === 0);
console.log(data); // Output: 2

2. Filtering string from the array

const fruits = ['Apple', 'Banana', 'Orange'];
const filteredData= fruits.find(fruit => fruit== 'Orange');
console.log(filteredData); // Output: Orange

3. Filtering Objects in an Array

const employees = [
  { name: 'John', age: 38 },
  { name: 'Tom', age: 37 },
  { name: 'Mathew', age: 35 },
  { name: 'Andrew', age: 30 },
];

const data = employees.find(employee => employee.age > 36);
console.log(data); // Output: { name: 'John', age: 38 }
