Know the answer? Post it — somebody with the same question will find it here.

try this

Const value=Math.random()<0.5?"a":"b"
 if(value !="a") 
{ } else if(value=="b")
 { }

your code should be
const data = Math.random() < 0.5 ? "a" : "b";
if(data ==="a")
{
}
else if (data ==="b")
{

}
!=="a" means ==b, so your else block will never execute.

If this is C# code then define the type for the constant value varibale and use the paranthesis with the ternary operator to aviod confusion for compiler. Also 'const' keyword is all in small. You will get syntax error for this part of the code i.e.
const string value=Math.random() < (0.5?"a":"b")
Know that first your comparision operators are wrong, secondly, this is logical error as string is not a native data type, its an object and by default it does not have any operator overloads for it. You can either overload the !=, == etc or you can simply use the string object function 'Equals(..)' for comparision. With your code you might not get the acurate comparision, so, it is not recommended to use comparision operators with string data types, but, the functions which are part of this object. Use comparision as below i.e.
if(!value.Equals("a"))
{
}
else if(value.Equals("b"))
{
}
