Python is already used in the back-end of most web-based applications. However, it does not work with the front-end of web browsers in those applications. This is where Transcrypt comes in. Transcrypt can help create more coherent web-based projects where Python is used to write the back-end and front-end. This course is primarily about using a transpiler called Transcrypt. It translates our Python code to JavaScript and then executes that JavaScript, letting us enjoy the neatness of Python with the front-end flexibility of JavaScript.
