Break Down the Problem

1. Identify the Question: What kind of scoping does JavaScript use?
2. Options Available:
   • Literal
   • Lexical
   • Segmental
   • Segmental (listed twice, likely a typo)

Relevant Concepts

1. Understanding Scoping:

   • Scoping refers to the visibility and lifetime of variables in programming languages.
   • JavaScript is known for its unique handling of scope, particularly with the introduction of ES6.

2. Types of Scoping:

   • Lexical Scoping: Variables are accessible within the local scope and in nested scopes where they are defined.
   • Other types: Literal and Segmental are not standard terms used in JavaScript.

Analysis and Detail

1. Evaluation of Options:
   • Literal: Not applicable to JavaScript scoping.
   • Lexical: Correctly describes JavaScript's mechanism where scope is determined by the physical placement of the code.
   • Segmental: Not commonly used in reference to JavaScript.

Verify and Summarize

1. Correct Option: Based on established JavaScript principles, the correct answer is "Lexical".
2. Summary: JavaScript uses lexical scoping which is defined by the location of variables in the source code structure.

Final Answer

The correct answer is Lexical.
