To check if an object has a specific property in JavaScript, you can use the in operator or the hasOwnProperty() method. Here's an example of how to use both approaches:
In this example, we define an object myObj with two properties: foo and baz. We then use the in operator to check if myObj has the foo property and the hasOwnProperty() method to check if myObj has the baz property.
Both methods will return true if the object has the specified property, and false otherwise. The in operator checks for the property in the object's prototype chain as well, while the hasOwnProperty() method only checks for properties that are directly defined on the object.
