JavaScript Course | Execution Contexts. EXECUTION CONTEXT, NEWENVIRONMENT
Hi! This is a new course from AvitoTech engineers—joined by front-end developer Vasily Novikov, we'll explore the basic technologies of web development in JavaScript.
In this video, web developer Vasily Novikov will discuss the basic algorithms for creating an environment record and demonstrate how to initialize the execution context.
In this new episode, you'll learn about:
— Three types of environment records: LexicalEnvironment, VariableEnvironment, and PrivateEnvironment;
— The steps of each of the four execution context algorithms;
— Initializing the global execution context.
