Don't know how you get hello in the first place because you've used "==" which is used for comparison and "=" used for assignment of a variable.

var demo = "hello";

var flag ="0"; //now the value is assinged with help of "="

if( flag == "0"){ // compare value of flag with 0 with help of "==" 
  console.log('sucess' + demo); // i am getting this value
  if(flag == "0"){
    console.log(demo); // not able to access here
  }
  else {
  };
}
else{
}

var demo = "hello";

var flag = 0;

if( flag === 0){
  console.log("sucess" + demo); 
  if(flag === 0){
    console.log(demo); 
  }
  else { }
}
else{ }

Use var flag="0" not var flag=="0" .Its assignment not comparison. Values are assigned using single = operator while comparison uses == or === operators to compare values. Both aren't the same.

var demo = "hello";

var flag ="0";

if( flag == "0"){
  console.log('sucess' + demo); // i am getting this value
  if(flag == "0"){
    console.log(demo); // not able to access here
  }
  else {
  };
}
else{
}
