Which of the following is the correct way to define the edit function in a custom Gutenberg block?
Afunction edit() { <p>Hello Block</p>; }
Bdef edit(): return '<p>Hello Block</p>'
Cedit = function() { echo 'Hello Block'; }
Dconst edit = () => { return <p>Hello Block</p>; };
Step-by-Step Solution
Solution:
  1. Step 1: Identify JavaScript syntax for Gutenberg blocks

    Gutenberg blocks use modern JavaScript with arrow functions for edit.
  2. Step 2: Check each option's syntax

    const edit = () => { return <p>Hello Block</p>; }; uses arrow function returning JSX, which is correct. function edit() { <p>Hello Block</p>; } does not return the JSX element. edit = function() { echo 'Hello Block'; } uses PHP syntax, and B uses Python syntax, both invalid here.
  3. Final Answer:

    const edit = () => { return <p>Hello Block</p>; }; -> Option D
  4. Quick Check:

    Gutenberg edit uses JS arrow functions [OK]
Quick Trick: Gutenberg edit uses JavaScript arrow functions returning JSX [OK]
Common Mistakes:
  • Using PHP or Python syntax instead of JavaScript
  • Not returning JSX properly
