根据我们的要求进行数组拆分

var myString = 'raju,rani,raghu,siva,stephen,varam';
var array = myString.split(',');

var array = [ 'raju', 'rani', 'raghu', 'siva', 'stephen', 'varam' ];
var result = {};

for(var i = 0; i < array.length; i+= 2) {
   result[array[i]] = array[i+1];
}

undefined

var array = ['raju', 'rani', 'raghu','siva','stephen','varam'], 
    pairs = {};

for (var i = 0; i < array.length; i += 2) {
    pairs [array[i]] = array[i + 1];
}
