What is Forbidden constructor, use a literal or simple function call instead error by gulp tslint? [duplicate]

Question

I am working on angular 2 application using ag-grid plugin and gulp as build tool -

   #225 function onPageSizeChanged(pageSize) {
   #226     this.pageSize = new Number(pageSize);
        createNewDatasource();
    }

I am getting below error message for above code -

[gulp-tslint] error app/app.component.ts[226, 21]: Forbidden constructor, use a literal or simple function call instead

Please let me know if this information is not sufficient, I will provide further details. Thanks in advance.

Answer 1

Just

this.pageSize = pageSize;

What's the intention of using new Number(pageSize); anyway?
