How do I escape curly braces in Angular

Question

I have this in my HTML:

<iframe src="https://kart.1881.no/?direction={59.83006424|6.25588723|START}{{{latitude}}|{{longitude}}|M%C3%85L}"></iframe>

Notice {{{latitude}} - Here I want to escape the first {

I tried to put \{ but it not work as well.

The error is Missing expected : at the end of the expression

Answer 1

Simply try

{{'{' + latitude + '}'}}
