Answer 1

When assigning a function to a variable, you need a semicolon after the function.

Example: var func = function() { return false; };

Answer 2

Put a semicolon after all statements. JavaScript does this automatically for you when you “forget” the one at the end of the line **, but since you used the tool to keep everything on the same line, this no longer happens.

First, start with a raw, human-written version of your javascript, you know, an unimimized non-automatic version

After the correction, you are convinced that it is free from syntax errors ... and you minimize it, do not make mistakes when copying / pasting
