So that let is the extension function for to create the template class which takes the lambda as the parameter, for applying the contract on it and it ultimately returns the execution of the lambda values which we passed as the parameters on it. And also it will return the object itself from that the scope function or we can even return the result of the operation or operations from the scope function. Scope functions are nothing but the functions which define the scope of the calling object we can apply the operations on that object within that scope.
Like kotlin scope is one of the function types and it is used to for to providing the features like extension functions, nullability checks, and much more. In the kotlin language, we used a lot of default keywords and functions used for implementing the kotlin mobile-based application. We can use let function in different areas based on the requirement. The above code is the basic syntax for utilizing the let keyword and function in the kotlin language.
