Sum of alternating 2 elements

I have an array like this c=[1,2,3,4,5,6,7,8,9,10]

if I want to execute the sum of each alternating two elements, like 1+2, then 5+6, then 9+10, how the code should be written? I can do the sum of each 2 elements.

You could simply use a for loop do so.

var c=[1,2,3,4,5,6,7,8,9,10]
var sum = [];

for (var i = 0; i < c.length; i += 2)
  sum.push(c[i] + c[i+1])

for (var j = 0; j < sum.length; j++)
  console.log(sum[j]);
