ReferenceError: time is not defined

Variable times seems undefined, but as a newbie to js, can't understand whats the prob. Tried to declare var time globally then incremented inside condition but not working.

var j1 = 0;

var j2 = 0;

var j3 = 4;



var time;



if((j1||j2||j3)>=3){

    

    

   time+5000;



    while(time === 30000){

        if(j1>=3){

            alert("Junction 1 is flooded");

        }else if(j2>=3){

            alert("Junction 2 is flooded");

        }else if(j3>=3){

            alert("Junction 3 is flooded");

        }else if ((j1&&j2)>=3){

            alert("Junction 1 & 2 are flooded");

        }else if ((j1&&j3)>=3){

            alert("Junction 1 & 3 are flooded");

        }else if ((j2&&j3)>=3){

if((j1||j2||j3) >= 3) is a non sense, you can't factorise conditions such way.

time+5000; doesn't do anything for you because time is undefined because all you did was declare, but not initialize it with:

var time; // Declared but not initialized === undefined

and you can't do math with undefined.

Additionally, you aren't capturing the result of the math operation.

Make it:

var time = 0; // Declared and initialized ;)

and then:

time = time + 5000; // Assign result of expression back to variable

Next, your if conditions are incorrect. Tests for multiple values must be done individually, so this:

if((j1||j2||j3)>=3){

needs to become this:

if(j1 >= 3 || j2 >= 3 || j3 >=3){

Lastly, the way your code is now, time will only ever be incremented once, to a value of 5000, so you will never enter into your while loop. Then, even if do enter your loop, you don't modify the value of time within it, so the loop will never end. You need to set up some kind of condition to check to determine if the loop should continue. It should be something like:

while(time < 50000){

  if(time === 30000){

    if(j1 >= 3){

        alert("Junction 1 is flooded");

    }else if(j2 >= 3){

        alert("Junction 2 is flooded");

    }else if(j3 >= 3){

        alert("Junction 3 is flooded");

    }else if (j1 >= 3 && j2 >=3){

        alert("Junction 1 & 2 are flooded");

    }else if (j1 >= 3 && j3 >= 3){

        alert("Junction 1 & 3 are flooded");

    }else if (j2 >= 3 && j3 >=3){

        alert("Junction 2 & 3 are flooded");

    }else if (j1 >= 3 && j3>=3){

        alert("Junction 1 & 3 are flooded");

    }else if (j1 >=3 && j3 >=3 &&j2 >=3){

        alert("All 3 junctions are flooded");

    }

  }



  time = time + 5000;  // <-- You need to create a situation where the loop can end! 

}

So, putting it all together:

var j1 = 0;

var j2 = 0;

var j3 = 4;



var time = 0;



if(j1 >= 3 || j2 >= 3 || j3 >=3){



  while(time < 50000){

      // Check what time is with an "if"

      if(time === 30000){

        if(j1 >= 3){

            alert("Junction 1 is flooded");

        }else if(j2 >= 3){

            alert("Junction 2 is flooded");

        }else if(j3 >= 3){

            alert("Junction 3 is flooded");

        }else if (j1 >= 3 && j2 >=3){

            alert("Junction 1 & 2 are flooded");

        }else if (j1 >= 3 && j3 >= 3){

            alert("Junction 1 & 3 are flooded");

        }else if (j2 >= 3 && j3 >=3){

            alert("Junction 2 & 3 are flooded");

        }else if (j1 >= 3 && j3>=3){

            alert("Junction 1 & 3 are flooded");

        }else if (j1 >=3 && j3 >=3 &&j2 >=3){

            alert("All 3 junctions are flooded");

        }

      }



      time = time + 5000;  // <-- You need to create a situation where the loop can end! 

    }

}

You should set time equal to 0 and use += to increment it.

var time=0;



if(j1>=3||j2>=3||j3>=3){





   time+=5000;

Just writing var time; is the same as var time = undefined and you can not perform mathematical operations on undefined. You need to initialize the variable.

To increment the time variable, you need to set it to 5000 plus itself or time = time + 5000 or as shorthand, time += 5000.

while(time === 30000) will always be false, and if it's true, it will result an infinite loop

time+5000; doesn't do anything for you because time is undefined because all you did was declare, but not initialize it with:

var time; // Declared but not initialized === undefined

and you can't do math with undefined.

Additionally, you aren't capturing the result of the math operation.

Make it:

var time = 0; // Declared and initialized ;)

and then:

time = time + 5000; // Assign result of expression back to variable

Next, your if conditions are incorrect. Tests for multiple values must be done individually, so this:

if((j1||j2||j3)>=3){

needs to become this:

if(j1 >= 3 || j2 >= 3 || j3 >=3){

while(time < 50000){

  if(time === 30000){

    if(j1 >= 3){

        alert("Junction 1 is flooded");

    }else if(j2 >= 3){

        alert("Junction 2 is flooded");

    }else if(j3 >= 3){

        alert("Junction 3 is flooded");

    }else if (j1 >= 3 && j2 >=3){

        alert("Junction 1 & 2 are flooded");

You should set time equal to 0 and use += to increment it.

var time=0;



if(j1>=3||j2>=3||j3>=3){





   time+=5000;

Just writing var time; is the same as var time = undefined and you can not perform mathematical operations on undefined. You need to initialize the variable.

To increment the time variable, you need to set it to 5000 plus itself or time = time + 5000 or as shorthand, time += 5000.
