Creating a function that returns a variable to ZERO if variable is NaN


Creating a function that returns a variable to ZERO if variable is NaN

With these it helps I am trying to store the value "0" within a variable if the variables calculation returns "NaN"
code :
// sample initialization
var score = 10;
var votecount = 'abc';

// first do the division
var division = score/votecount;

// check the division if it is NaN
if(isNaN(division))
  alert('zero'); // or return 0;
else{
  division = Math.round(division); // use division for the rest of the code
  alert(division);
}

Referencing variable,it executes the function,however adding strings to the variable,returns function as string instead

help you fix your problem The program is supposed to be a live search using php and javascript... where as you type it searches below. I just recently started learning javascript so sorry if my knowledge is limited...
code :
var newText = getText;
var newText1 = getText1;
var newText = getText();
var newText1 = getText1();
var newText = document.getElementById('year').value;
var newText1 = document.getElementById('class').value;

I wish did fix the issue. It looks like your function apiGet returns an xhr (request object). This will execute asynchronously, so that responseText isn't available until the response comes back from the server. When you call the property directly on the return, it happens so fast that the server hasn't responded yet, but when you use the console manually, by the time you type out result.responseText and press enter, the result is already in.
Just a guess of course, since I haven't seen the contents of getApi.

Hope this helps I would try to reframe the problem you're thinking about. If you're only thinking in terms of functional programming then yes, you're correct in that safety vs. more code is the basic trade off you're looking at.
However, there are a number of ways to get around your dilemma by reframing the problem. I obviously don't know what your code looks like, but it might be meaningful to think about building this functionality into a class. Rather than using global variables, set those values as class attributes with appropriate getters/setters, and then structure the module such that your functions become methods.

I think the issue was by ths following , This is pretty much impossible to do now in PowerShell so I've opened an issue You should be able to set the type conversion attribute on a variable with New-Variable to address this.

will be helpful for those in need I'm not recommending that you should actually use it, but makeActiveBinding() will do what you're asking for:
