Vue string matching in handlebars myString !== “” ? myString : otherString

myString !== "" ? myString : otherString is currently printing myString which is an empty string
What is wrong with my comparator? I also tried using single quotes
The reason I ask this seemingly basic question is because the Vue documentation on handlebars doesn't seem to cover this, aside from letting me know that general javascript is available, I thought this comparator was general javascript for strings

DoesmyString.trim() !== ""perhaps have an effect on the output? CanmyStringbe null or undefined instead of""?

@JonathanLonowski yes it can. The model says myString should be a string but the mongodb object may not have that key, currently

The ternary operator works fine on the template.
Check your myString data it might not be empty.
<div>Empty: myString === "" ? 'test' : otherString<div>
<div>Non Empty: myString !== "" ? 'test' : otherString<div>
See the example below.
var app = new Vue(
el: '#app',
data()
return
myString: "",
otherString: "blah"
,
)<script src="https://cdn.jsdelivr.net/npm/vue@2.5.17/dist/vue.js"></script>
<div id="app">
<div>Empty: myString === "" ? 'test' : otherString<div>
<div>Non Empty: myString !== "" ? 'test' : otherString<div>
