SyntaxError: missing } after function body (Firefox)
Error type
What went wrong?
There is a syntax mistake when creating a function somewhere. Also check if any closing curly braces or parenthesis are in the correct order. Indenting or formatting the code a bit nicer might also help you to see through the jungle.
Examples
Forgotten closing curly bracket
Oftentimes, there is a missing curly bracket in your function code:
function charge() {
if (sunny) {
useSolarCells();
} else {
promptBikeRide();
}
Correct would be:
function charge() {
if (sunny) {
useSolarCells();
} else {
promptBikeRide();
}
}
It can be more obscure when using IIFEs or other constructs that use a lot of different parenthesis and curly braces, for example.
(function () {
if (Math.random() < 0.01) {
doSomething();
}
)();
Oftentimes, indenting differently or double checking indentation helps to spot these errors.
(function () {
if (Math.random() < 0.01) {
doSomething();
}
})();
