Is it correct to execute a function inside IF else statement?

The isCheck() function returns false if not radio buttons have been checked.

if (isCheck() === false) {
        i = 0;
        return i;
      }

yes it works. alternatively you could use ternary operator using that syntax:

test ? expression1 : expression2

for example :

 //init var i with some value
 var i = 1;
 function isCheck(){ return false;}

 i = isCheck() === false ? 0 : i;
 return i;

or simple:

 //before you should initialize i
 return !isCheck()  ? 0 : i ;

Yes it is correct

enter image description here

You dont need to create a variable only to receive a bool and later do a validation you can do directly.

There is no wrong in executing a function inside if conditional statement.

For such case you can use ternary operator

var i=-1; // Note var key word & initialized with some value
  isCheck() === false ? (i=0):(i=someOtherVal)
