Course outline and revision prompts
Module 1
JS: Web foundations
Apply JS through standards, structure, developer tools.
Lesson
Key terms
Revision question
Standards with JS
standards, JS, webdev
In JavaScript Foundations and Practice, which evidence best supports a standards result produced with JS?
Structure with ES2024
structure, ES2024, webdev
In JavaScript Foundations and Practice, which evidence best supports a structure result produced with ES2024?
Developer tools with Async
developer tools, Async, webdev

Standards: from context to evidence
Standards connects user and browser need to a tested interface in JavaScript Foundations and Practice.
1User and browser need
Define the purpose, intended user and JS constraints.
frames
2Standards
Use valid semantics and test more than one browser and input method.
produces evidence for
3Tested interface
Compare the observed result with a normal case, boundary case and stated limitation.
Takeaway: Standards is credible only when the result can be traced back to its purpose, inputs and constraints. Standards is the decision layer between the starting context and evidence that the result is fit for purpose.
Module 2
ES2024: Core implementation
Apply ES2024 through components, state and data, responsive layout.
Lesson
Key terms
Revision question
Components with DOM
components, DOM, webdev
In JavaScript Foundations and Practice, which evidence best supports a components result produced with DOM?
State and data with JS
state and data, JS, webdev
In JavaScript Foundations and Practice, which evidence best supports a state and data result produced with JS?
Responsive layout with ES2024
responsive layout, ES2024, webdev
In JavaScript Foundations and Practice, which evidence best supports a responsive layout result produced with ES2024?

Components connects user and browser need to a tested interface in JavaScript Foundations and Practice.
1User and browser need
Define the purpose, intended user and DOM constraints.

2Components
Extract repeated UI while keeping state at the narrowest useful boundary.

3Tested interface
Compare the observed result with a normal case, boundary case and stated limitation.
Takeaway: Components is credible only when the result can be traced back to its purpose, inputs and constraints. Components is the decision layer between the starting context and evidence that the result is fit for purpose.
Module 3
Async: Quality
Apply Async through accessibility, testing, performance.
Lesson
Key terms
Revision question
Accessibility with Async
accessibility, Async, webdev
In JavaScript Foundations and Practice, which evidence best supports a accessibility result produced with Async?
Testing with DOM
testing, DOM, webdev
In JavaScript Foundations and Practice, which evidence best supports a testing result produced with DOM?
Performance with JS
performance, JS, webdev
In JavaScript Foundations and Practice, which evidence best supports a performance result produced with JS?

1User and browser need
Define the purpose, intended user and Async constraints.

2Accessibility
Check semantics, keyboard order, names, contrast and zoom.

3Tested interface
Compare the observed result with a normal case, boundary case and stated limitation.
Takeaway: Accessibility is credible only when the result can be traced back to its purpose, inputs and constraints. Accessibility is the decision layer between the starting context and evidence that the result is fit for purpose.
Module 4
DOM: Production practice
Apply DOM through security, deployment, maintenance.
Lesson
Key terms
Revision question
Security with ES2024
security, ES2024, webdev
In JavaScript Foundations and Practice, which evidence best supports a security result produced with ES2024?
Deployment with Async
deployment, Async, webdev
In JavaScript Foundations and Practice, which evidence best supports a deployment result produced with Async?
Maintenance with DOM
maintenance, DOM, webdev
In JavaScript Foundations and Practice, which evidence best supports a maintenance result produced with DOM?

Security: from context to evidence
Security connects user and browser need to a tested interface in JavaScript Foundations and Practice.
1User and browser need
Define the purpose, intended user and ES2024 constraints.
frames
2Security
Validate on the server, encode output and apply least privilege.
produces evidence for
3Tested interface
Compare the observed result with a normal case, boundary case and stated limitation.
Review the evidence, adjust the method, and repeat.
Takeaway: Security is credible only when the result can be traced back to its purpose, inputs and constraints. Security is the decision layer between the starting context and evidence that the result is fit for purpose.
Course practical outcome
Produce a reviewable JavaScript Foundations and Practice project using JS, ES2024, Async.
Expected output: A working JavaScript Foundations and Practice artefact plus an evidence-based self-review.
Tools: A suitable JS environment, A plain-text decision log, Test data or realistic sample material
Production steps
Define the intended user, outcome and constraints.
Create the smallest complete result using JS.
Test one normal case, one boundary case and one failure response.
Revise the work from the evidence and preserve before-and-after results.
Prepare a concise handover containing method, limitations and next step.
Success criteria
The output matches the stated outcome.
Inputs and decisions are reproducible.
Boundary and failure evidence is included.
Limitations and responsibility considerations are explicit.
Self-review
Can another learner repeat the method?
Did I test a difficult case?
Did I avoid unsupported claims?
Is the next action proportionate to the remaining risk?
Next step: Choose one weakness found during review and improve it before extending the JS scope.
