Reset to default 5 
delete myJsonObj.employees[1];

However, this will keep the index of all the other elements. If you want to re-order the index, too, you could use this:

// store current employee #0
var tmp = myJsonObj.employees.shift();
// remove old employee #1
myJsonObj.employees.shift();
// re-add employee #0 to the start of the array
myJsonObj.employees.unshift(tmp);

Or you use simply Darin Dimitrov's splice solution (see his answer below).

myJsonObj.employees.splice(1, 1);

Use delete:

delete myJsonObj.employees[1]

or set it to null

myJsonObj.employees[1] = null;

Neither will affect the indices of any elements following the element deleted from an array.
