TypeScript is a compartmented superset of JavaScript that compiles to plain JavaScript. It includes a number of advanced features that can help you develop larger and more complex programs more fluently. Some exemplifications of advanced TypeScript features include.
Generics: These allow you to write flexible and applicable law that can work with multiple types.
Decorators: These are a way to add fresh functionality to your law, using a declarative syntax.
Generics:
Generics allow you to produce applicable factors that can work with multiple types. Then’s an illustration of a general function that returns the minimal value in an array:
In this example, the function min is defined with a type parameter T, which is used to specify the type of the rudiments in the array. The function can be called with an array of any type, and the type of the rudiments in the array will be inferred by the compiler. The returned value will have the same type as the rudiments in the array.
Decorators:
One advanced point of TypeScript is the capability to use decorators. Decorators are a design pattern that allows you to add fresh geste to an being class or system.
Here is an example of using a decorator to define a method that will be run before a class method is executed
In this example, the logExecutionTime decorator function is defined and then applied to the myMethod method of the MyClass class using the @ symbol. When myMethod is called, the decorator function will be run first and will log the execution time of the myMethod method.
