TypeScript

Function overloading (or Method Overloading) is a feature where two or more functions can have the same name but with different parameters and implementations. The function overloading is not available in JavaScript. But Typescript does allow us to create several overload signatures of a function. We can use those overload signatures to call the function and thus mimicking the function overloading. Let us learn how to create an overloaded function in TypeScript using examples

The Type Aliases in Typescript allow us to give a custom name to an existing type. This is useful when you wish to reuse an existing type as it provides a reusable definition.

In this tutorial, let us look at the objects and learn how to create the object type and assign it to objects. objects are the most fundamental data type in TypeScript. The Typescript has seven primitive data types string, number, bigint, boolean, undefined, symbol, and null. Anything that is not a primitive data type is an object. Understanding objects and creating types to represent them is crucial in learning TypeScript. In this tutorial, we will learn what objects are in TypeScript and how to create types for objects and use them.

unknown type means that the type of variable is not known. It is the type-safe counterpart of any. We can assign anything to an unknown variable, but the unknown isn’t assignable to any other types except to unknown and any. To use an unknown type, we need to first assert its type or narrow it to a more specific type.

noImplicitAny compiler option when set to true prevents TypeScript from implicitly assuming the type as any when the type is not specified or type cannot be inferred from its usage.
