Answer 2

Line 24:
Can't use <prev> as variable name for the button reference cause it's a function's name.

Line 25:
Can't use <next> as variable name for the button reference cause it's a function's name.

Line 26, 27:
1. Typo for method name, it should be "addEventListener"

2. Don't use parentheses () after function name when mapping event handler to a function. Just put the name without ().

<element>.addEventListener( "click", <function-name> );
