String Replacer

string_replacer.js

// Write a function that will take a string with word placeholders (ie. "Hello __NAME__"), and an
// options object (ie. {name: "James"})and return that string with placeholder words replaced by values
// in the options object (ie. "Hello James")

// For this example, we can assume that each __PLACEHOLDER__ in the string will have a corresponding key in the options object.
// So the word `__PLACEHOLDER__` in the string will have a key value of `placeholder` in the options object. Let's look
// at a quick example:

// const string = "James loves to play __SPORT__ on __DAYOFWEEK__"
// const opts = {sport: "soccer", dayOfWeek: "Sunday"};

// Once passed through our stringReplacer function, the output should be:
// "James loves to play soccer on Sunday".

// Some things to think about:
//
// 1) The format of the placeholder is slightly different than the key in the options object, so how can we match them together?
// 2) We don't know what the string passed in will be, so there could be any amount of different placeholders
//    in a the string given to us, however we do know that each different placeholder in the string will for sure have a
//    corresponding key in the options object
//
// I look forward to seeing your thought process in solving this problem!

const stringReplacer = (string, opts) => {
  // Code here
};

const string = '__NAME__ came to our __EVENT__ and __ACTION__';
const opts = {
  name: 'Jared',
  event: 'movie',
  action: 'loved it'
};

console.log(stringReplacer(string, opts));
// The correct output here should be: "Jared came to our movie and loved it"
