Application function of in-place call in JavaScript
Let's use an in-place function call as one of the terms:
let sum = 1 + function() {
return 2;
}();
console.log(sum); // shows 3
Determine what will be output to the console without running the code:
let result = function() {return 1;}() + function() {return 2;}();
console.log(result);
