The dynamic part can use an array literal for the different colors, and use the dynamic value as index for that array:

Both ratings and averageRating should be virtual fields: otherwise, the /0 division is going to crash your schema the moment you have an entry in your collection with product.ratings = 0. So what I would do is, firstly, define ratings by a getter function for a virtual field:

If you notice that when logging rating is equal to {rating: "4"} which is your req.query the value you want is actually req.query.rating so try something like

const rating = req.query.rating

or

const { rating } = req.query

I would recommend always using '===' instead of '==' when strict equality checking is required, which it is in most cases, for this reason: it declares intent. When I see code with '===', I will read it as 'a must be referentially or primitively equal to b'. When I see '==', I will read it as 'a must be coercibly equal to b'. From that, I will judge what kind of goal the code / original programmer is trying to accomplish and how they are passing data around to get the job done. Essentially, it yields insight into the context of the application, the way data is being passed around, and how this function / method / code block fits into the picture.

With that being said, if I see someone do 'a == b' when they are both strings, I'm not going to get on any high horse and make a fuss about it.

PR should be updated automatically. If that doesn't happen try changing the target branch to something else and changing it back to main.

The idiomatic way is an if statement with a comparison against null:

Short answer: control flow narrowing is heuristic in nature and does not account for such correlations between variables. There is an open issue at microsoft/TypeScript#20497 requesting support for so-called "branch flags" like your allGood. But it is probably too complex to implement.

Long version:

TypeScript uses control flow analysis to narrow the apparent types of variables and properties in blocks of code where it can follow that type guards or assignments have occurred. So, for example, in the following example code, the compiler can see that a truthiness check on a will narrow it from number | undefined to number:

when you write y = 'the value', x, 'is truthy', you are setting y to be a tuple, as you are setting it to multiple values separated by commas. For it to be a simple string, you can use concatenation:
y = 'the value '+ str(x) + ' is truthy'
or string formatting:
y= 'The value {0} is truthy'.format(x)
The reason this issue does not arise when you write it directly into a print statement like print('the value', x, 'is truthy') is the way that function parameters work: each comma separated value is passed as another argument into the function, and the print statement simply prints each argument out. So when you write it like this, each comma separated item is treated as a different item and printed, rather than all placed in a tuple which you are then printing out as a whole when you assign it to a variable such as in y = 'the value', x, 'is truthy'

The problem is that || has higher operator precedence (6) than the conditional operator (4). So the two initial expressions you have (the options.format and JSON.parse`) get grouped together first:
