JavaScript file should not get generated if Typescript file has any error

Question

Consider below Typescript code

class formal
{
    private startString: String = "";
    constructor(startString:String)
    {
        this.startString = startString;
    }

    public sayHello = function() :Number {
       alert(this.startString);
    }     

}

var myIntro = new formal("hello world");
myIntro.sayHello();

Currently It has following error "A function whose declared type is neither 'void' nor 'any' must return a value. An object that represents a number of any kind. All JavaScript numbers are 64-bit floating-point numbers."

But after running tsc command it is generating corresponding js file. What I need is that it should not generate corresponding JS file until all the errors are resolved of typescript file.

Is there any way to achieve this?

add --noEmitOnError to your compiler.

It would properly look something like this: tsc myFile.ts -w --noEmitOnError

If you are interested in other compiler settings, the command tsc -h will show all options
