  delete items[items.indexOf('c')];
}
console.log(items)
alert(items)
alert(items.length)

Use JavaScript Array's built in splice method:

array.splice(index, 1);

The second parameter is the number of elements to remove, so 1 = "just this one".

"c" may be at any place.So First I need to get the index of c ?

Then use indexOf() method along with this one.
