+# Seven Boom!
+[Edabit Problem](https://edabit.com/challenge/6R6gReGTGwzpwuffD)
+
+Create a function that takes an array of numbers and return `"Boom!"` if the digit 7 appears in the array. Otherwise, return `"there is no 7 in the array"`.
+
+Examples:
+```javascript
+sevenBoom([1, 2, 3, 4, 5, 6, 7]) ➞ "Boom!"
+// 7 contains the number seven.
+
+sevenBoom([8, 6, 33, 100]) ➞ "there is no 7 in the array"
+// None of the items contain 7 within them.
+
+sevenBoom([2, 55, 60, 97, 86]) ➞ "Boom!"
+// 97 contains the number seven.
+```
