I am trying to get params from my component

    import { Component } from '@angular/core';

    @Component({
      selector: 'data',
    })
    export class Data {
      constructor(public title: string, public p: string,) {}
    }

then when I import it to my page and I define my var

import { Data } from '../../components/data/data';

dataList: Data[];

I’m getting this error: Cannot find name ‘Data’
