JavaScript
JavaScript is a programming language based on the ECMAScript standard. It is often used to make websites and other programs respond to actions and change over time.
Another example
A web app receives a checked form event and a JSON reply. JavaScript updates the app's data and tells the user the result. Browser tools such as the DOM are provided to the language, not part of JavaScript itself.
Main parts
- 01values and objects
- 02execution context
- 03modules
Use it when
Use this term for ECMAScript code, how it runs, modules, objects, or language rules.
Do not use it when
Do not mix up JavaScript with Java, the DOM, Node.js, or one web framework.
Name used in code
import → execute → state Before you ship
Check the runtime and version, integration limits, dependencies and licenses, and platform support. Verify security, failure, speed, monitoring, deploy, support owner, upgrade path, and rollback.
Outcome: Use or review JavaScript as a technical building block that the team can maintain. User context: A web app receives a checked form event and a JSON reply. JavaScript updates the app's data and tells the user the result. Browser tools such as the DOM are provided to the language, not part of JavaScript itself. Technology or engineering concept: JavaScript. Why it fits: Use this term for ECMAScript code, how it runs, modules, objects, or language rules. Do not use it when: Do not mix up JavaScript with Java, the DOM, Node.js, or one web framework. Engineering fit: Define where it runs and which version to use. Set its job, interfaces, data flow, dependencies, supported systems, security, and speed limits. Explain how it fits the current stack. Lifecycle safeguards: Check dependency health and licenses. Add monitoring and a fallback. Name the upgrade owner. Do not add a second tool for the same job without a measured benefit. Acceptance criteria: A small integration proves the needed behavior. Test compatibility, security, failure, and performance. Document deploy, upgrade, support, and rollback steps. Evidence and limits (evidence boundary): The standard covers only the listed scope. It does not choose the visual style, product decision, or Vibulary example. Unknowns to confirm: Current stack, runtime and version rules, target systems, dependency owner, performance budget, support period, and migration limits.

Review the current use of JavaScript. Definition: JavaScript is a programming language based on the ECMAScript standard. It is often used to make websites and other programs respond to actions and change over time. Release checks: Check the runtime and version, integration limits, dependencies and licenses, and platform support. Verify security, failure, speed, monitoring, deploy, support owner, upgrade path, and rollback. Before changing code, report the evidence you found, gaps, severity, and the smallest safe fix.
