Benchmark: countNeighbours - MeasureThat.net

Script Preparation code:

var row = 1;
var col = 2;
var data = [[1, 0, 0, 1, 0],
            [0, 1, 0, 0, 0],
            [0, 0, 1, 0, 1],
            [1, 0, 0, 0, 0],
            [0, 0, 1, 0, 0]];

Tests:

Reduce
return data.reduce((r, v, i) => i>row+1 || i<row-1 ? r : v.reduce((c, v, i) => i>col+1 || i<col-1 ? c : c + v, r), 0) - data[row][col];
getCell
function getCellValue(r,c) { return (data[r]&&data[r][c])?data[r][c]:0; }; return getCellValue(row-1,col-1)+getCellValue(row-1,col)+getCellValue(row-1,col+1)+getCellValue(row,col-1)+getCellValue(row,col+1)+getCellValue(row+1,col-1)+getCellValue(row+1,col)+getCellValue(row+1,col+1);
