Typescript: How to Check Type of Objects & Variables

The process of ensuring that the types of objects or variables used in a program are correct and conform to the expected types is known as type-checking.

In TypeScript, you can use the in operator, instanceof operator, and typeof operator to check the type of objects and variables.

Yes! The typeof operator can be useful for checking the type of primitive values such as strings, numbers, and booleans. However, when working with objects, classes, and arrays, it may not work as expected. In these cases, you may want to consider using other type-checking techniques such as the instanceof operator or the in operator.
