If statement in this exercise

Question

I was wondering how you would check if the inputs from the user were equal to a numeric value.
How would the if statement look like? Can you use the following for example?
if ( number1 && number2 != parseInt() ) {
  alert("Please enter a number");
}
I don't know if the parseInt is appropriate but I'm just curious in what ways you can check this.

javascript
if ( number1 && number2 != parseInt() ) { alert("Please enter a number"); }

First - you need to evaluate every condition separately , then add the condition  &&, you logic make sense to me, but not to the javascript interpreter.
>>  number1 != parseInt() && number2 != parseInt()
Second - you are right parseInt() requires a parameter, and it must be present when you call for parseInt... so it should be something like:
>>  parseInt(numberPicked,10);
third - the alert will show and it will ask, but there is no request to enter a number, 
>>you need to use prompt()
most importantly, and I think what you are looking for  as an answer:
 javascript interpreter scan the file, notice the variables, and "mark them"   but doesn't store them, and read and store functions, look for articles about  *Hoisting** 
Best Luck !
