Introduction to Dart Programming Language

What is Dart?

Dart Programming Language is developed by Google which is a client-optimized programming language. The development process on Dart Programming Language is very fast which supports multiple platforms, i.e, Dart Programming Language by Google is used to build mobile, desktop, backend and web applications.

Dart Programming Language is an open-source, object-oriented, garbage-collected, general-purpose, class defined language that uses a C-style syntax that transcompiles optionally into JavaScript. Dart Programming Language also supports both loose and strong typing.

Dart is a Static as well as Dynamic Type programming language. It also supports Type Infarant with the pre-defined keyword var.

Plush sign "+" is the concatenation operator in the Dart programming language.

Static Types means if a developer defines a variable as string you can not assign other type value (like integer, double, etc) in that string type variable.

Type Infarant means if the developer uses the var keyword to define a veriable then the developer will store any data type variable in the defined variable with the var keyword.

Dart Programming Language supports two types of compilation, that is, AOT (Ahead Of Time) and JIT(Just In Time) compiler.

Just In Time (JIT) compilation done at the run time.

Dart Code --> JIT compile duting development (D:\> dart dartProgram.dart) --> Run the program (Output)

Ahead Of Time (AOT) compilation is done at the end of the final product deployment with sone optimization.

Dart Code --> AOT compile at the end of development (D:\> dart dartProgram.dart) --> Run the program (Output)
