The `length` Property
The length property can be used to quickly get the amount of elements in an array:
12let numbers = [5, 7, 9, 10, 15, 25, 30, 35]; console.log("There are", numbers.length, "numbers in the array.");
A property is a variable associated with an object. It represents an attribute or characteristic of that object. In this case, the length is a property of the array object, and it returns the number of elements in the array. You can access properties the same way you access methods: objectName.propertyName.
1. What does the length property of an array return?
2. What will be the output of the following code?
