As per Wikipedia: A compiled language is a programming language whose implementations are typically compilers (translators that generate machine code from source code). Compilers help translate languages like C++ and Java into bytecodes that the machine can understand and execute. We review their content and use your feedback to keep the quality high. The main goal of both compilation and interpretation is to transform the human-readable source code into machine code that can be executed directly by a CPU, but there are some caveats to it. On the contrary, JavaScript is an interpreted language. If a bit of code is executed often, let's say 100 times (exact number depends on the browser) it is considered "warm". TypeScript is a strongly typed, object oriented, compiled language. How to create and type JavaScript variables. For any TypeScript files it finds there, it will output the compiled JavaScript to a new folder named output. In general, it is considered an interpreted language. This means static typing permits to check type accuracy at compile time. It means that the only correct compilation would need to create a whole model (simulator) of target system with embedded interpreter which would be used during runtime. What is Interpreted Language?

Since it is an interpreted language, errors can only be found during run-time. In sum, TypeScript is JavaScript with additional features developed to overcome JavaScript setbacks, especially when it comes to static typing and handling code complexity. One of the common although not ideal ways to differentiate them is to split them into 2 groups compiled and interpreted languages. Abstract syntax tree interpreter. Compilers and interpreters take human-readable code and convert it to computer-readable machine code. If the idea of a compilation step confuses you keep in mind that JavaScript is already compiled and then interpreted. So it is not the right term to call these errors as compiler errors. The TypeScript compiler also preserves the original file path, hence the . TypeScript is a typed superset of JavaScript compiled to JavaScript. How to provide types to JavaScript ES6 classes. Still, most languages are considered either "compiled" or "interpreted" because they are most commonly implemented with a compiler or interpreter. TypeScript is both a language and a set of tools. It's passed to the V8 engine and interpreted from it's text form, so in that sense it's interpreted. As you can see, the TypeScript compiler compiled all the input TypeScript files listed inside files array of tsconfig.json. Numeric enums. At run time, the V8 engine actually compiles and executes bytecode version of the javascript, so at a low level, it is being compiled before it's run. This compilation happens dynamically and at runtime, so you don't need to worry about it as a programmer. Types of compiled language - C, C++, C#, CLEO, COBOL, etc. An interpreted language is one that is primarily executed either as source code or bytecode through a dedicated virtual machine.

But, more recent versions are compiled, at least partially. In this sense, C++ is compiled and Python is interpreted. JavaScript is a lightweight interpreted programming language.
