Array.prototype.find() — find string by length

📖 Usage Example

const words = ['cat', 'elephant', 'dog']
words.find(w => w.length > 4)  // → 'elephant'

Use find() to retrieve the first string from an array that meets a length or content condition.

Array.prototype.find() — strings

find() works with any element type. You can use it to find strings satisfying a length or content condition.

Challenge: Implement findLongest(strs) that returns the first string with more than 5 characters.

findLongest(['hi', 'hello', 'greetings']) // → 'greetings'
findLongest(['a', 'bb', 'ccc'])           // → undefined
