    \"cent\": \"200\",
    \"triplet\": \"222\"

Answer 1

Try this

// Iterate thorugh the array
[].forEach.call(x, function(inst, i){
    // Iterate through all the keys
    [].forEach.call(Object.keys(inst), function(y){
        // Check if string is Numerical string
        if(!isNaN(x[i][y]))
            //Convert to numerical value
            x[i][y] = +x[i][y];
    });

});

console.log(x);
