Sometimes, we may run into the ‘SyntaxError: return not in function’ when we’re developing JavaScript apps.
In this article, we’ll look at how to fix the ‘SyntaxError: return not in function’ when we’re developing JavaScript apps.
Fix the ‘SyntaxError: return not in function’ When Developing JavaScript Apps
To fix the ‘SyntaxError: return not in function’ when we’re developing JavaScript apps, we should make sure we’re using return and yield property inside a function.
On Edge, the error message for this error is SyntaxError: 'return' statement outside of function.
On Firefox, the error message for this error is SyntaxError: return not in function and SyntaxError: yield not in function .
For instance, if we have:
const cheer = function(score) {
if (score === 147)
return 'Maximum!';
};
if (score > 100) {
return 'Century!';
}
}
then we’ll get the error since the first if statement is missing the opening curly brace.
To fix it, we write:
const cheer = function (score) {
if (score === 147) {
return "Maximum!";
}
if (score > 100) {
return "Century!";
}
};
