In the context of closures, what is meant by the term 'lexical scoping' in JavaScript?

  • Lexical scoping, also known as static scoping, means that the scope of a variable is determined by its position within the source code, and it is fixed at the time of the variable's definition. In JavaScript, closures have lexical scoping, which means they capture variables from the outer function based on where they are defined in the code, not where they are executed.
  • Lexical scoping, also called static scoping, refers to the way variables are resolved in a program. In JavaScript closures, lexical scoping means that the scope of a variable is determined by its location in the source code, and it remains fixed once the function is defined.
  • Lexical scoping, often referred to as static scoping, is a feature of closures in JavaScript. It means that a closure captures variables from its surrounding context based on their lexical location, not their runtime values. This allows closures to access variables even after the outer function has completed execution.
  • In JavaScript closures, lexical scoping means that the scope of a variable is determined by its position in the code when the closure is defined, not when it is executed. This ensures that closures capture the correct variables from their enclosing scope.
