JSON and JAVASCRIPT differences and code difference

Javascript Array: 

var obj = []; 

obj.push = 'Some VALUE'; Or var obj = ['SomeVALUE', 1, 2]; 

now to access them use obj[0] -- 0 stands the index No. 

*********************************************** 

JSON Array and manipulations: 

Example 

var obj = { name : value, anotherName : anotherValue };  // if JS Variable used

var obj = { 'name' : 'value', 'anotherName' : 'anotherValue' }; // if JS Strings are used

Or Else

 ips[ipId] = {}; 

ips[ipId]['name'] = value; 

ips[ipId]['anotherName'] = anotherValue;

now - 

JSON.stringify(object); // gets you the string of the JSON Object

// No need to parse, no need to use JSON.parse as the variable holds the JSON Object only.

if you want to create a JSON Object from string or reverse engineer JSON.stringify() Method then use JSON.parse();

Also, You can use string variables to specify the names of the properties:

var name = 'name'; // name is variable - changing its value often

obj[name] = value; // note that their are no single quotes near name variable;

name = 'anotherName';

obj[name] = anotherValue;a
