Description: The ‘Execution Context’ refers to the environment in which a piece of code runs, encompassing both the state of variables and the execution scope and available functions at that moment. This concept is fundamental in programming as it determines how code instructions are interpreted and executed. In an execution context, different levels can be distinguished, such as the global context and local contexts created when invoking functions. Each time a function is called, a new execution context is generated that includes its own variables and parameters, allowing for encapsulation and modularity of code. Additionally, the execution context influences error handling and how resources are accessed. Understanding the execution context is essential for developers as it allows them to optimize code performance and avoid issues such as variable name collisions or accessing unwanted data. In summary, the ‘Execution Context’ is a key concept underlying program execution and the management of memory and resources in modern programming.
