E0062: missing name or parentheses for function
If a statement begins with the function
keyword, the declared function must
have a name. It is an error to start a statement with function
but not give a
name to the function:
function() { // IIFE for our module
class PublicClass {}
class PrivateClass {}
window.PublicClass = PublicClass;
}()
function (number) {
return number % 2 === 0;
}
[1, 2, 3, 4].filter(isEven)
.forEach(number => console.log(number));
To fix this error, wrap the IIFE (Immediately Invoked Function Expression) in parentheses:
(function() { // IIFE for our module
class PublicClass {}
class PrivateClass {}
window.PublicClass = PublicClass;
}())
Alternatively, write the name of the function after the function
keyword:
function isEven(number) {
return number % 2 === 0;
}
[1, 2, 3, 4].filter(isEven)
.forEach(number => console.log(number));
