# Check if an Object has a Property (freeCodeCamp Challenge)
## "Basic Data Structures" ➡️ Chapter 5
## Part of the JavaScript Certification ➡️ Lesson 17
### There are 2 ways to check for the existence of an object property:
1. `objectName.hasOwnProperty("propertyToCheck");`
2. `propertyToCheck in objectName;`
that, applied to this challenge, become:
1. `peopleOnProjectObj.hasOwnProperty("Agnese"), peopleOnProjectObj.hasOwnProperty("Rian"), peopleOnProjectObj.hasOwnProperty("Michelle"), peopleOnProjectObj.hasOwnProperty("Aiden")`
2. `"Agnese" in peopleOnProjectObj && "Rian" in peopleOnProjectObj && "Michelle" in peopleOnProjectObj && "Aiden" in peopleOnProjectObj`
#### 🎯 Complete the Challenge:
Finish writing the function so that it returns *true* if the object passed to it contains all 4 names:
- `Agnese, Rian, Michelle` and `Aiden`
and returns *false* otherwise [^1]
[^1]: Double and single quotes are interchangeable in JavaScript
