How Javascript Execution Works at Jimmy George blog

How Javascript Execution Works. An execution context can be thought of as a container that holds all the necessary information about the current state of the program. It explains how the javascript engine executes code, the runtime, and its components. An execution context has two phases: ⚙️ everything in javascript happens inside an execution context These two components work together to facilitate the proper execution of javascript code while managing variable. The first execution context created is the global execution context. In this blog, we'll take a closer look at the process of javascript execution and some key concepts you need to know. Javascript codes are executed in contexts. When the javascript engine scans a script file, it makes an environment called the execution context that handles the entire. It also helps them stay. But have you ever wondered, how javascript code actually gets executed? Javascript execution context is the environment in which javascript code is executed. It contains information about the variables, functions, and objects that are available to the code being executed, as well as the scope chain and the value of the 'this' keyword. This includes variables, functions, and objects that are currently available within the current scope. Understanding how javascript operates behind the scenes shapes the way developers approach problems and write more efficient codes.
