Resolving TypeError: “X” is Not a Constructor in JavaScript

A constructor in JavaScript is a special function that creates and initializes an object instance of a class, invoked using the new keyword. It sets values for object properties and can use the "this" keyword to refer to the new object instance. Constructors allow the creation of multiple objects and can accept parameters to assign different property values to each instance. In contrast to object literals, which create a single object, constructors are advantageous for generating multiple unique objects. Additionally, properties and methods can be shared across all instances by adding them to a constructor's prototype. While JavaScript provides built-in constructors like Object, String, and Number, using primitive data types is recommended for better performance. Tools like Rollbar offer automated monitoring and error management to enhance deployment confidence by tracking and analyzing errors in real-time.
