Apex and Lightning development

Customise Salesforce with code.

📖 Key ideas

  1. Apex is Salesforce's Java-like language.
  2. SOQL queries data: SELECT Name FROM Account WHERE Industry = 'IT'.
  3. Triggers run Apex on record events; keep logic in handler classes.
  4. Governor limits restrict resources per transaction; bulkify code.
  5. Lightning Web Components (LWC) build modern UIs with JavaScript.
💡 Real-life example: Governor limits are a shared kitchen rule: no cook may use all the stoves at once.
