find() array method in javascript

Array methods were introduced in javascript in ES5. Before this, every array iteration was performed by loops. But after the introduction of array methods to perform array operations, work on an array has become very easy without the implementation of extra coding.
Here we will discuss some array methods.
find()
This method gives the first condition passed element. If no elements pass the given condition it gives an undefined return value. It is not valid for empty arrays. It does not change the original array.
