SyntaxError: return not in function
The JavaScript exception "return (or yield) not in function" occurs when a
return
or yield
statement is called outside of a function.
Message
SyntaxError: 'return' statement outside of function (Edge)
SyntaxError: return not in function (Firefox)
SyntaxError: yield not in function (Firefox)
Error type
What went wrong?
A
return
or yield
statement is called outside of a function. Maybe there are
missing curly brackets somewhere? The return
and yield
statements must be in a function, because they end (or pause and resume) function
execution and specify a value to be returned to the function caller.
Examples
Missing curly brackets
var cheer = function(score) {
if (score === 147)
return 'Maximum!';
};
if (score > 100) {
return 'Century!';
}
}
// SyntaxError: return not in function
The curly brackets look correct at a first glance, but this code snippet is missing a
{
after the first if
statement. Correct would be:
var cheer = function(score) {
if (score === 147) {
return 'Maximum!';
}
if (score > 100) {
return 'Century!';
}
};
