SyntaxError: missing } after function body

The JavaScript exception "missing } after function body" occurs when there is a syntax mistake when creating a function somewhere. Check if any closing curly brackets or parenthesis are in the correct order.

There is a syntax mistake when creating a function somewhere. Also check if any closing curly brackets or parenthesis are in the correct order. Indenting or formatting the code a bit nicer might also help you to see through the jungle.

Oftentimes, there is a missing curly bracket in your function code:

var charge = function() {
  if (sunny) {
    useSolarCells();
  } else {
    promptBikeRide();
};

Correct would be:

var charge = function() {
  if (sunny) {
    useSolarCells();
  } else {
    promptBikeRide();
  }
};

It can be more obscure when using IIFE, Closures, or other constructs that use a lot of different parenthesis and curly brackets, for example.

(function() { if (true) { return false; } );

Oftentimes, indenting differently or double checking indentation helps to spot these errors.

(function() {
  if (true) {
    return false;
  }
});
