The malfunction of return statement in JavaScript when using Angular

I'm having an issue with my Angular code not working when it's written in a certain format. Here is the code:

app.directive("strength", function() {
return 
{
    require: "superhero",
    link: function(scope, element, attrs, superheroCtrl) {
        superheroCtrl.addStrength();
    }
  }
})

However, if I place the first curly bracket of the return object on the same line as the return statement, then the code works fine: Here's the updated code that works.

app.directive("strength", function() {
    return {
        require: "superhero",
        link: function(scope, element, attrs, superheroCtrl) {
            superheroCtrl.addStrength();
        }
    }
})

Is there something else I am missing or doing incorrectly? How can I solve this issue? Any help would be greatly appreciated! Thank you!

Answer №1

When it comes to syntax, the first scenario triggers automatic semicolon insertion right after the return statement. In the second case, when defining an object literal with key/value pairs, it results in a syntax error unless assigned.

Essentially, your code is interpreted as follows:-

return; //<-- Statement ends here
 {
    require: "superhero", //<-- Syntax error occurs here
    link: function(scope, element, attrs, superheroCtrl) {
        superheroCtrl.addStrength();
    }
  };

The return statement encounters automatic semicolon insertion (ASI), where no line terminator between the return keyword and the expression is permitted.
