--description--

To toggle the visibility for the text, you will need to first create a function that will be responsible for that behavior.

Start by creating a new function called handleToggleVisibility.

--hints--

You should have a handleToggleVisibility function.

js
// Tried using isDefined and isFunction here but it didn't work. assert.match works though
assert.match(code, /function\s+handleToggleVisibility\(\)\s*\{[\s\S]*\}|(const|var|let)\s+handleToggleVisibility\s*=\s*\(\)\s*=>\s*\{[\s\S]*\}/);
