** Understanding JavaScript Execution Context and Single-Threaded Model
JavaScript, a powerful programming language, relies on execution context and single-threaded model for efficient code execution. Execution context refers to the environment where code runs, comprising global execution context, function execution context, and lexical environment. The Call Stack is used to manage these contexts. Additionally, JavaScript operates on a single-threaded model, meaning it executes only one command at a time. This concept is crucial for developers as it helps write efficient code and troubleshoot issues.
