I wanna get number of total array in NodeJS. Any way can do this?
For example: In picture have array from 0 > 558. Then I want a function to give the count is 559
Thank you.
Hieu
The array is only broken in console since it is very long: (i.e: if the length of array is longer than 100 then the console will break it to show it clearly..). if u logged the length then it will show 559, just do arr.length

I've got this array in my jquery Script :
I want to count all items inside my array called div.item.bloc-membre
Right now I have this code that returns me 75
console.log($(response).length);
Thanks for your help !
Using filter
console.log($(response).filter("div.item.bloc-membre").length);

I am trying to understand what it means when a code appears in between the brackets. I know that has something to do with an array.
In the case of "inputArray[0]", it is finding the value at index position 0 (the first element) in the array "inputArray".

I saw this in someones code and i'm trying to understand what it means
if(output=="" && history!=""){
if(isNaN(history[history.length-1])){
history = history.substr(0, history.length-1);
}
}
'history' is an Array
the secound line is checking if the last item of 'history' array is not a number, if so, the third line deletes the last item in the array
