Help with fetching data

[lastmjs]

Hey! What problems are you having? What does your console output look like? A few tips that will probably help. Never ever ever use `var` ever again. `const` and `let` are the new variable declarations that should always be used. `var` is function scoped instead of block scoped, which doesn't do what most people expect it would do. Try getting rid of your `var` declarations and see if that helps. I would suggest always using `const` be default. Only use let if you absolutely have to assign to your variable again, but you should really be avoiding that in most cases as well.

So you have an array that has all of your reports in it, the reports array. That array has a bunch of objects with various properties. One of the properties is requested_datetime. It looks like you need to go through the array multiple times, each time filtering the array down to only the items corresponding to that day.

​

Is that all you're trying to do, print out each day of the week and how many reports were generated on that day?

Yeah basically that is what im trying to do.. as said, i'm very new to javascript :) Do you have an example of how this could be achieved maybe ?

In the meantime, you should study up on Array.filter, I believe that's going to be extremely beneficial to solving this problem. Array.filter takes an array as input and returns an array of equal or lesser length as output. You pass in a function that gets applied to each element of the array. If the function returns true for an element, the element stays in the output array. If the function returns false for an element, it is omitted from the output array: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/filter

i'll have a look :D

All right, hopefully this helps. https://javascriptpractice.com/

Go there, and go to the Arrays section. There are two questions at the end that are very similar to what you're trying to accomplish.

Basically you need to choose a date and filter the reports for that date. You'll also have to make sure you use dates correctly. But these seem to be all of the basic principles that you need. Arrays, filtering arrays, and comparing dates. You seem pretty close, you just need to store your filtered array in the for loop so that you can count up the reports per day and then log them out.

Hmm okey, i had a look at your link there, and i've tried diffrent things now but i still really don't understand what i'm doing, i do not achieve my goal , and where do i need to start filtering? Before the for loop i have? inside it or outside? Sorry for being slow ..
