Error: Cannot read properties of undefined (reading ‘toLocaleString’)
This error occurs when you try to access properties or methods of an undefined value or object. The error message specifically mentions the ‘toLocaleString’ method, but this concept applies to other properties or methods as well.
Explanation:
When you attempt to access properties or methods on a value that is not defined (undefined), JavaScript throws an error. The ‘toLocaleString’ method is used to convert a date or number into a localized string representation, but in this case, the value you are trying to use it on is undefined.
Example:
Let’s consider an example where you have a variable that is expected to hold a date value:
const date = undefined;
const dateString = date.toLocaleString();
In the above example, the ‘date’ variable is undefined. Therefore, when you try to call the ‘toLocaleString’ method on it, the error “Cannot read properties of undefined (reading ‘toLocaleString’)” is thrown. To fix this error, you need to ensure that the ‘date’ variable holds a valid date object before using ‘toLocaleString’ or any other properties/methods on it.
