If statement Javascript using variable from other file

Question

I have a problem with my javascript code.

numbercars.js

var cars = {
chan1:'',
number:'2';}

index.html

<html>
    <head>
    <script type="text/javascript" src="numbercars.js"></script>
    <script>
    var numbercars = cars.number;

    if (numbercars =<9){
    //My action
    }
    else{
    //My second action
    } 
    </script>
    </head>
    <body>
       HTML CONTENT
    </body>
</html>

But this statement didn't work, all time, it's else.

Can you, if you can, tell me where is my error, i didn't understand.

Thank you

@OrryVandermeulen first file numbercars.js who I declare the number of Cars. The second file is index.html who I need to make a statement from the number of cars. Exemple : if number >2, I can do an action, if <2, I can't do nothing — Argardor, Feb 10 '18 at 18:28
What happens if you `console.log(cars)` in your second `script` tag? It seems to me that you are not loading the script properly. Are the files in the same directory? — nicodp, Feb 10 '18 at 18:47

You have two issues

A semi-colon in your cars object. Remove it.

var cars = {
    chan1:'',
    number:'2';
}
              ^

You're using an invalid combination of operators to compare numbers. Change to numbercars <= 9

if (numbercars =< 9){
               ^

Remove the semi-colon and quotation marks for integers.

var cars = {
  chan1:'',
  number: 2
}
