How is this equal to 10 var arr =[1,2,3,3,2,0] var x = 0 for (var i=1; i<arr.length; i++){ x+= arr[i] } alert(x)
The calculation should be 0 https://code.sololearn.com/WUFk4Avd3YDi/?ref=app

in your code var=1 makes
x+= arr[1] start at second position in array.
changing code to var=0 makes
x+= arr[0] start at first position in array.
ALL arrays start at 0
