Kotlin Beginner Tutorials (Cheezy Code)

A complete Kotlin language series in Hindi from Cheezy Code, 41 short lessons and about 5 hours, the natural first step before Android development. It sets up IntelliJ, explains compilation to bytecode, var and val, data types, operators and short-circuiting, if and when as expressions, ranges, loops and string templates, functions with default and named arguments, overloading and arrays. The OOP section covers classes, primary and secondary constructors, getters, setters and lateinit, inheritance, overriding, polymorphism, abstract classes, interfaces, smart casts, visibility modifiers, object declarations and companion objects, data, enum and sealed classes. It finishes with null safety, exceptions, collections, lambdas and higher-order functions, map and filter, extension and scope functions, and generics.
