javascript - How to round some values in an object array? - 


 array = [ {name:apples, price:3.99, tax:0.20},             {name:oranges, price:1.40, tax:0.15},            {name:bananas, price:0.99, tax:0.10},           ]

how run tofixed() on "price" values (and not names, performance purposes) come this:

 array = [ {name:apples, price:4, tax:0.20},             {name:oranges, price:1, tax:0.15},            {name:bananas, price:1, tax:0.10},           ]

will have go through loop route?

just loop on array (btw: never use array variable name):

for (var i=0; i<arr.length; i++)     arr[i].roundedprice = math.round(arr[i].price);
