I want to export the variable 'myVariable' from getVariable.ts

export class getVariable {

      myVariable: number = 0;           

}

And use it in my html to show a button or not: I tried to import the .ts but there is no value in the variable 'myVariable'. How can I import the variable?

 <button type="button" id="btn1" class ="btn1"> btn1 </button>
 <button type="button" id="btn2" class="btn2"> btn2 </button>
 <script>          
                                import {getVariable } from "../getVariable ";
                                var statement = getVariable.myVariable;
                                if (statement != 0) {
                                    document.write('<button type="button" id="btn3" class="btn3"> btn3 </button>');
                                }
                                  
 </script>
