The possibility to define an interface in addition to the classes we define appeared for the first time in the Java programming language. Since then, in most programming languages that have appeared, the option to define an interface (in addition to the classes) has been added. These languages include C#, Kotlin, PHP, and many others. The TypeScript programming language also allows you to define interfaces.
The Use of Interfaces in Programming Languages
The interfaces have many uses in programming languages. The Java Programming course on life michael academy goes over these uses in detail. One of the derivatives of these uses is the well-known rule of thumb to define variables with types that were defined as interfaces (in cases where possible) and in this way allow greater flexibility for changes in the code.
The Unique Uses of Interfaces in TypeScript
The TypeScript programming language has unique characteristics (such as its support for Structural Typing). As a result, interfaces have uses unique to the TypeScript programming language.
The Interfaces in TypeScript Seminar
The Interfaces in TypeScript seminar thoroughly explains the uses unique to TypeScript and the uses known in any other programming language that supports interfaces.
