I have the following object called checkObj. I'm trying to use a for... in loop to see if the object contains the property foundNum. Since it does exist, the purpose of the program is to then reassign the value of "found" to 1 as shown below.
    const checkObj = {
      oddNum: 1,
      evenNum: 2,
      foundNum: 5,
      randomNum: 18
    };
    
    let found = 0;
    // ADD CODE HERE
    
    for (foundNum in checkObj) {
      if (object.key(checkObj).includes = foundNum ) {
        let found = 1
      }
    }
However, I get the following error: Reference Error on line 11: foundNum is not defined. I'm not very familiar with for... in loops so not sure how to fix this bug.
