. // now let's set a user answer on a question // we can assume that we get both the question index // and the answer index for the question from elsewhere in javascript // for example from clicking on … In a real application you may also add something like a quiz rendering class to be able to render the quiz using javascript (and to separate display of quiz from core quiz objects). …

I am concerned that you have added a layer of false generalization around a very specific, usually one-time use, request object. I would think the class would be better named Request or similar to be …

Outside of the other answers about the general utility of this function, I figured I would add some additional thoughts on the code itself. I do agree with those other opinions though that this functi …

A few thoughts: First, you might consider whether the name/color property REALLY needs to change as output here. Why return { color: ... } in some cases and { name: ... } in others? This tends to i …

Your nested "ifs" make the code very hard to read. I would think about changing your approach to something like if (undefined === vm.masterFormObject) { console.log('Some error message.'); r …

I would consider formulating the output for this custom function to return values of 1, 0, and -1 (a typical javascript approach for comparing two values), such that this function could be used as a custom …

I would think that this might be a problem best solved via recursion. For example: function flattenArray(arr) { var result = []; arr.forEach(function($val) { if(Array.isArray($val)) …

I guess I don't really see what value you are getting from these functions. Isn't the following in essence the same thing without ~100 extra lines of code that don't really do much other than provid …

I would agree with answer from @JosephtheDreamer that, as a beginner in javascript, this is probably a domain area you don't want to tackle unless your intent is just to deep clone simple array and object … I would also strongly suggest that, if you are just learning javascript, you do so based on ES6 and get familiar with that syntax. …

That might look like this: (function() { // your javascript code }()) This would prevent you from defining a bunch of variables in global scope which could interact negatively with other javascript …

product * value, 1); return numbers.map( (value) => arrayProduct / value ); } One could also easily foresee a case where larger arrays could easily hit up against the Number.MAX_SAFE_INTEGER value in javascript …

I think I would consider something like this: const data = { teaching_levels: null, axes: null, accessibility_resources: null, contents: null, resources: null, licenses: resul …

Not sure that a class definition makes a lot of sense here since you don’t really have any real behavior being defined in this class. Destructuring can also help you populate variables from the inpu …

Both of these seem horribly inefficient, but I guess that is what you get if you are forced to use recursion to solve this problem. In either case you don't validate input. What if you don't get an …

Some thoughts: This is not truly a recursive function, in that you are not passing the path value when first calling the function. This may hint that you should really just recurse privately within …
