Add following code in to your script.

//Your JSON Data

var empdata = {

 content: {

     employee: [

       {

         name: "Joe",

         Age: 30,

         id : 1007

       },

       {

         name: "Bill",

         Age: 35,

         id : 1008

       }

     ]

  }

};

//Create Class

var Employees = React.createClass({

render: function() {

  //To retrieve keys from data.content

  var keys = Object.keys(empdata.content);

  //iterate through the keys to get the underlying values

  var allEmps = keys.map((t) => empdata.content[t].map((e) => ({e.id}-{e.name}-{e.Age})));

return ({allEmps})

}

});

//Render data to HTML

ReactDOM.render(, document.getElementById("root"));

Get first letter of each word in a sentence

 private string GetAcronym(string strSiteName)
        {
            string shortName = string.Empty;
            string[] txtArray = strSiteName.Split(' ');
     
       //if site name is a single word, get the first three characters of the site name
                if (txtArray.Length == 1)
                {
                    return strSiteName.Substring(0, 3);
                }

                //Get the first letter of each word in the site name
                foreach (string word in txtArray)
                {
                    shortName += word.Substring(0, 1);
                }
                return shortName;

Unit testing Vs Integration testing Vs System testing Vs UAT Vs Smoke testing

Unit Testing
- Unit testing is a method by which individual units of source code are tested to determine if they are fit for use.
- Unit tests are created by programmers or occasionally by white box testers during the development process.


Integration testing
- Individual software modules are combined and tested as a group.
- System integration testing is the process of verifying the synchronization between two or more software systems and which can be performed after software system collaboration is completed.
- It occurs after unit testing and before system testing
- The purpose of integration testing is to verify functional, performance, and reliability requirements placed on major design items


System testing
-  Once the system testing is done  the software is ready to ship
-  Done by QA at development end
- System testing of software or hardware is testing conducted on a complete, integrated system to evaluate the system's compliance with its specified requirements. System testing falls within the scope of black box testing, and as such, should require no knowledge of the inner design of the code or logic.
- It is also intended to test up to and beyond the bounds defined in the software/hardware requirements specification(s).


UAT
- User acceptance testing is testing conducted by users of the system
- Done by QA(trained like end users


Smoke testing
- Smoke testing refers to the first test made after assembly or repairs to a system, to provide some assurance that the system under test will not catastrophically fail. After a smoke test proves that "the pipes will not leak, the keys seal properly, the circuit will not burn, or the software will not crash outright," the system is ready for more stressful testing.

Deploying Assembly in GAC vs BIN

If you are frequently updating the Assembly, then you always better to deploy it in BIN.  Since, Assembly will be reloaded automatically just after the updating.    But when you update the Assembly in GAC, you have to restart the IIS (IISRESET) to grab the new version. The reason is GAC keeps the assembly in Cache.

When you deploy your Assembly on GAC then you can access the Assembly from any SharePoint web application. But when you deploy Assembly in web application’s BIN folder, then it can only access from the given web application. Anyway, if you have all-purpose web part, you better to deploy it in GAC and avoid the multiple Assembly deployments in BIN. 

If you have multiple versions of same Assembly, then you have to deploy it in GAC. Coz, GAC manages the multiple version of given Assembly, but BIN doesn’t
