why the syntax parser wont inject a semicolon in var after carriage return but in function t the return got injected ?

var a = 5
+
5
console.log(a); //results 10

function t(){
 return
 5
}

console.log(t()); //results undefined

Expressions in JavaScript do not end at the end of the line. Thats where semicolons are important. return is a complete statement on its own and has automatic semicolon insertion.
