Exploring an array to retrieve a specific value

Can someone assist me?

I am looking to create a JavaScript function that follows the structure of the code example below. Unfortunately, I do not have enough programming skills to develop a functional solution from scratch.

The goal is to input a value, search through an array using that value, and return the corresponding short name (the value on the right side of the colon character).

function findShortName() {

var filenames = {
        "REQUEST FOR INFO": "REQI",
        "MEDIA CALL": "MC",
        "ISSUES NOTE": "ISN"
    };

EX1.)

    var value_to_search_for = "REQUEST FOR INFO (ALPHA)";

    if (filenames[value_to_search_for]) {

        return filenames[value_to_search_for];

    }

EX2.)
    var value_to_search_for = "MEDIA CALL";

    if (filenames[value_to_search_for]) {

        return filenames[value_to_search_for];

    }

}

Answer №1

You have the option to convert it into an object and proceed with this approach

var filenames = {
  "REQUEST FOR INFO": "REQI",
  "MEDIA CALL": "MC",
  "ISSUES NOTE": "ISN"
};

var getValue = function(val, obj) {
  if (val in obj) return obj[val];
}

console.log(getValue('ISSUES NOTE', filenames));

You can also opt for an array of objects and then you can perform this action

var filenames = [
  {"REQUEST FOR INFO": "REQI"},
  {"MEDIA CALL": "MC"},
  {"ISSUES NOTE": "ISN"}
];

var getValue = function(val, array) {
  array.forEach(function(el) {
    for (prop in el) {
      if (prop == val) console.log(el[prop]);
      }
    });
  }

getValue('MEDIA CALL', filenames);
