New Line '\n' is not working in Typescript

\n does not cause a line break in html.
You'll need to use a <br/> or wrap your text in a block element.

this.includeValues += this.merId + ',' + this.explodeStatus + '<br/>';
this.excludeValues += this.merId + ',' + this.explodeStatus + '<br/>';

Or

this.includeValues += '<div>' + this.merId + ',' + this.explodeStatus + '</div>';
this.excludeValues += '<div>' + this.merId + ',' + this.explodeStatus + '</div>';

Need to use fix width:

 <div style="width: 500px;white-space: pre-line">{{property}}</div>

In typescript use '\n' to add new line.
