Scope

Core JavaScript Concepts encompass variables (var, let, const), data types (string, number, boolean, object, array), operators (arithmetic, comparison, logical), and control flow structures (if-else statements, switch statements, loops), forming the foundational elements for building JavaScript programs.

Functions in JavaScript encompass function declaration vs. expression, arrow functions, scope and closures, callback functions, and higher-order functions, serving as essential tools for organizing and executing code efficiently.
