I have an array with subarrays and wish to sort numerically and descending by the first item in the subarrays. So for example, I wish to take the following array"
array = [[2,text],[5,text],[1,text]]
and sort it to become
array = [[5,text],[2,text],[1,text]]
Is there any simple function to use? Thanks!
array = [[2,text],[5,text],[1,text]];
array.sort(function(a,b){return a[0] < b[0]})
function genericSort(index, arr) {array.sort(function(a,b){return a[index] < b[index]})} and then you can call it as array = [[2,3],[5,1],[1,2]];genericSort(0, array); /*this will sort on the first index*/ genericSort(1, array); and this one on the second hope this could help
array = [[2,text],[5,text],[1,text]];
array.sort(function(a,b){return a[0] - b[0]})
working of the sort function
if the function returns
Additional information at source.
array.sort((a,b) => a[0] - b[0])array.sort(key=lambda x: x[0], reverse=True)
