#    
#  Overview
We can check if a certain element exists in an array by using the **`contains()`**  method.
#     
#  Syntax
```swift
arr.contains(elem)
```
#    
## Parameters
**`arr`**: This is the array we want to check to see if it contains a certain element.

**elem**: This is the element we want to check to see if it exists in the array `arr`.
##   
## Return value
A Boolean value is returned. `true` is returned if the element `elem` exists in array `arr`. Otherwise, it returns `false`.
##   
## Code example



// create arrays
let gnaam = ["Google", "Netflix", "Amazon", "Apple", "Meta"]
let vowels = ["a", "e", "i", "o", "u"]
let languages = ["C", "Swift", "Java"]

// check if some elements are present
print(gnaam.contains("Facebbok"));  // false 
print(gnaam.contains("Meta"))       // true
print(vowels.contains("a"))         // true
print(vowels.contains("z"))         // false
print(languages.contains("Python")) // false
print(languages.contains("C"))      // true

# Explanation
* In lines 2 to 4, we create the arrays `gnaam`, `vowels`, and `languages`.
* In lines 7 to 12, we invoke the `contains()` method on the arrays we created, and pass some parameters to it. We then print the results on the console.
