replace angular expressions with static values in a string

In an angular controller I have:

var stringTemplate = "{{data.a}} - {{data.b}}";
var data = {a: "example1", b: "example2"};

Is there a way to replace the expressions in stringTemplate with static values from data. So in this case the result should be "example1 - example2".

I need to store this in a database and use later when data is not available.

Values in data and stringTemplate will change.

You can use Template Literals syntax introduced in ES6.

var data = {
    a: "example1",
    b: "example2"
};

var stringTemplate = `${data.a} - ${data.b}`;

console.log(stringTemplate);

ES5: Using Regex

var data = {
    a: "example1",
    b: "example2"
};

var stringTemplate = "{{data.a}} - {{data.b}}";

stringTemplate = stringTemplate.replace(/\{{(.*?)}}/g, function($0, $1) {
    return data[$1.split('.')[1]] || $0;
});

console.log(stringTemplate);
