How to declare array of specific type in javascript

Question

Is it possible in java script to explicitly declare array to be an array of int(or any other type)?

something like var arr: Array(int) would be nice...

Answer 1

var StronglyTypedArray=function(){
      this.values=[];
      this.push=function(value){
      if(value===0||parseInt(value)>0) this.values.push(value);
      else return;//throw exception
     };
     this.get=function(index){
        return this.values[index]
     }
   }

EDITS: use this as follows

     var numbers=new StronglyTypedArray();
     numbers.push(0);
     numbers.push(2);
     numbers.push(4);
     numbers.push(6);
     numbers.push(8);
     alert(numbers.get(3)); //alerts 6

Array of specific type in typescript

export class RegisterFormComponent 
{
     genders = new Array<GenderType>();

     loadGenders()
     {
        this.genders.push({name: "Male",isoCode: 1});
        this.genders.push({name: "FeMale",isoCode: 2});
     }

}

type GenderType = { name: string, isoCode: number };    // Specified format
