JSLINT Syntax

JSLINT standards:

if(value != null){
Use '!==' to compare with 'null'.

if(name.dataIndex !='' || name.dataIndex != null){
Use '!==' to compare with ''.

if(rowIndex == 0){
Use '===' to compare with '0'.

data.push({description: obj['city'], required: true});
['city'] is better written in dot notation.
data.push({description: obj.city, required: true});  //dot notation as per jslint syntax

var obj = new Object();
Use the object literal notation {}.

//wrong
var x = {
        prop: 10
    },
    y = x["prop"];

//correct
var x = {
        prop: 10
    },
    y = x.prop;
