Replace {{ values }} in String

template.js

// This is a basic templating function. It replaces any {{key}} in the
// string with the corresponding value in data. If no data is provided,
// then the template is returned as-is.
//
// Example:
//   template("Hello, {{name}}!", { name: "John" }) → "Hello, John!"
//   template("Hello, {{name}}!") → "Hello, {{name}}!"

export function template(string, data = {}) {
  let out = string;

  for (const [key, value] of Object.entries(data)) {
    out = out.replace(`{{${key}}}`, value);
  }

  return out;
}
