    Digital technology, Internet and AI

    Understanding technology means distinguishing documentation, standards and sales descriptions. The site also offers a professional Web directory.

    Getting started

    Define the task, find MDN documentation and then locate the relevant W3C standard or group.

    Before deciding

    Check version, compatibility and usage context. Inclusion in this selection does not certify a website’s security.

    Choose a source and keep useful references

    Compare resources

    MDN explains technologies and usage; W3C publishes standards and work. Distinguish teaching examples, browser support and normative requirements.

    Prepare your research

    For a feature, note browser version, document consulted and behaviour observed in an example. Local execution does not prove universal compatibility.

    Practical questions

    Can an old code example still be used?

    Find function documentation and stated compatibility for your browsers. Try a minimal case and observe errors; a tutorial's date cannot replace checking the version actually in use.

    How can I check an AI-generated answer?

    Separate verifiable claims and open the cited original documents. Check that they exist and support the precise answer; retain uncertainty rather than treating confident wording as evidence.
