Check if an Object has a Specific Property

The hasProperty function checks whether a specific property exists in an object using the in operator.

const hasProperty = (obj, prop) => prop in obj;

const user = { name: "Alice", age: 25 };

console.log(hasProperty(user, "name"));  // true
console.log(hasProperty(user, "email")); // false
console.log(hasProperty(user, "age"));   // true

How it works:

• The in operator checks if the given property exists in the object, including inherited properties.

• It returns true if the property is present, regardless of its value (even if it's undefined).
