String transformation with `reduce()`

// mocked stuff
const stringTemplate = 'I’m sorry, {astronautName}. I’m afraid I can’t do that. This mission is too important for me to allow you to {unwantedThing} it.';

const values = {
    astronautName: 'Dave',
    unwantedThing: 'jeopardize'
};

// original function
function parseTemplate(stringTemplate, values) {
    for (var key in values) {
        if (values.hasOwnProperty(key)) {

        }
    }

    return stringTemplate;
}

// new function
// mind you, it happened in ES5 environment so no arrow functions this time
function parseTemplateFP(stringTemplate, values) {
    return Object.keys(values).reduce(function (string, key) {
        return string.replace(new RegExp('{' + key + '}', 'g'), values[key]);
