56533eb9ac21ba0edf2244c8	Accessing Object Properties with Bracket Notation	1	16163	accessing-object-properties-with-bracket-notation

--description--

The second way to access the properties of an object is bracket notation ([]). If the property of the object you are trying to access has a space in its name, you will need to use bracket notation.

However, you can still use bracket notation on object properties without spaces.

Here is a sample of using bracket notation to read an object's property:

const myObj = {
  "Space Name": "Kirk",
  "More Space": "Spock",
  "NoSpace": "USS Enterprise"
};

myObj["Space Name"];
myObj['More Space'];
myObj["NoSpace"];

myObj["Space Name"] would be the string Kirk, myObj['More Space'] would be the string Spock, and myObj["NoSpace"] would be the string USS Enterprise.

Note that property names with spaces in them must be in quotes (single or double).

--instructions--

Read the values of the properties an entree and the drink of testObj using bracket notation and assign them to entreeValue and drinkValue respectively.

--hints--

entreeValue should be a string

assert(typeof entreeValue === 'string');

The value of entreeValue should be the string hamburger

assert(entreeValue === 'hamburger');

drinkValue should be a string

assert(typeof drinkValue === 'string');

The value of drinkValue should be the string water

assert(drinkValue === 'water');

You should use bracket notation twice

assert(__helpers.removeJSComments(code).match(/testObj\s*?\[('|")[^'"]+\1\]/g).length > 1);

--seed--

--seed-contents--

// Setup
const testObj = {
  "an entree": "hamburger",
  "my side": "veggies",
  "the drink": "water"
};

// Only change code below this line
const entreeValue = testObj;   // Change this line
const drinkValue = testObj;    // Change this line

--solutions--

const testObj = {
  "an entree": "hamburger",
  "my side": "veggies",
  "the drink": "water"
};
const entreeValue = testObj["an entree"];
const drinkValue = testObj['the drink'];
