Array.prototype.some() — long string check

📖 Usage Example

const words = ['cat', 'dog', 'elephant']
words.some(w => w.length > 5)  // → true ('elephant')

Use some() to check whether any string in an array meets a length or pattern condition.

Array.prototype.some() — strings

some() works on arrays of any type. You can inspect string properties like .length inside the predicate.

Challenge: Implement hasLong(strs, minLen) that returns true if any string has length >= minLen.

hasLong(['hi', 'hello', 'hey'], 5) // → true
hasLong(['hi', 'hey'], 5)          // → false

💡 Hints (2)

• Access `.length` on each string inside the predicate: `s => s.length >= minLen`.
• `some()` stops as soon as the first matching string is found.
