handlebars js - How to avoid replacing handlebars placeholders / tokens with empty string, if they dont exist in the object passed in

I have template like this let str = "location = {{item.businessLocation}}";

And Data Object like this let data = {"item":{"name":"Mathew"}};

As we can see the placeholder or variable {{item.businessLocation}} is missing in the data object. I do not want the placeholder to be replaced with "" when it is rendered by Handlebars.

I tried implementing the helperMissing helper like below, but it did not work, because the placeholder has a dot in between.

handlebars.registerHelper('helperMissing', function(token) {
    return '{{'+token+'}}';
});

Is there any to have handlebars not replace tokens / placeholders with "" , if they don't exist in the object passed in?

I always get the below output

location = ""

What I need is

location = {{item.businessLocation}} 

( since item.businessLocation is not present in the data object )
