How to use Angular2 innerHTML expressions?

Question

I have:

<div [innerHtml]="myStr">

where:

this.myStr=='{{1+1}}'

I want it to display:

2

But it outputs:

{{1+1}}

In Angular1 $compile was used for this issue. What do we use in Angular2 to compile expressions?

i tried that link but it does not evaluate expressions in a string. It just dynamically creates components which are already defined but not yet instantiated. — danday74, Apr 12 '17 at 17:09
'{{ 1+1 }}' is an extreme simplification of my use case but if I can get '{{ 1+1 }}' working then I think I'm all good. — danday74, Apr 12 '17 at 17:10

{{ }} (double brackets) signals angular to interpolate values on the View, or client, not in the component class. You just want to set the value of this.myStr like a normal string variable in javascript.

following your example, you would use

this.myStr = '' + (1 + 1);

or

this.myStr = (1 + 1).toString();

You can use ES6 template strings:

this.myStr=`${1+1}`
