Uncaught TypeError If you are debugging your JavaScript code in Google Chrome, you may have seen this error for several times. This occurs when you call a method or read a property on an undefined object. Although this error can occur due to many reasons, a common one is the state of an element not properly initialized when UI components are rendered. Not only in JavaScript, this issue can also occur in an application developed using React JS or Angular jS. Let’s see how to fix it.

Fix – The state should be initialized using a reasonable default value in constructors.
