--description--
The second way to access the properties of an object is bracket notation ([]). If the property of the object you are trying to access has a space in its name, you will need to use bracket notation.
objectName["property name"];
Here is a sample of using bracket notation to read an object's property:
const spaceObj = {
"Space Name": "Kirk",
};
spaceObj["Space Name"]; // "Kirk"
Update your console statement to use bracket notation to access the property "Number of legs" of the cat object.
Open up the console to see the output.
--hints--
Your console statement should now have the value of cat["Number of legs"].
assert.match(code, /console.log\(\s*cat\[('|")Number\s+of\s+legs\1\]\s*\)/);
