Error: Cannot read properties of undefined (reading ‘location’)

This error message typically occurs when trying to access a property of an undefined object. It means that the variable you are trying to access has not been defined or has a value of undefined.

Here is an example to help you understand the error: 


    const person = {
      name: 'John',
      age: 25
    };

    console.log(person.location); // Error - Cannot read property 'location' of undefined

In this example, the variable `person` is an object with properties `name` and `age`. However, it does not have a property named `location`. So, when we try to access `person.location`, we get the mentioned error.

To resolve this error, make sure that the object and the properties you are trying to access are defined properly. You can add a conditional check to verify if the object exists before accessing its properties, like this: 


    if (person && person.location) {
      console.log(person.location);
    } else {
      console.log('Location is undefined');
    }

By adding a check for `person` and `person.location`, we avoid the error and can handle the undefined case gracefully.

This example provides an explanation of the error, including a sample code snippet demonstrating how the error can occur. It then shows a solution using a conditional check to prevent accessing properties on undefined objects.
