JavaScript Object Properties Quiz

Adding Properties to Objects in JavaScript

• An object is a fundamental data structure in JavaScript, allowing the storage of key-value pairs.
• To add a new property or update an existing property in an object, you can use dot notation or bracket notation.

Methods to Assign a Value to a Property

• Using bracket notation: fruits['name'] = 'apple';

  • This method uses brackets to specify the property name as a string.

• Using dot notation: fruits.name = apple;

  • This method uses a dot followed by the property name directly. Ensure the value is enclosed in quotes if it's a string: fruits.name = 'apple';.

Correct Code Options

• The correct way to assign the value involves ensuring that the string 'apple' is properly quoted.

• The valid options include:

  • fruits[name] = 'apple'; (incorrect without quotes around name)
  • fruits.name = apple; (incorrect without quotes)
  • fruits['name'] = 'apple'; (correct usage)

• Options imply an understanding that bracket notation and dot notation can be used interchangeably, depending on the scenario.

Conclusion

• The correct way to add a string 'apple' to the property 'name' in the fruits object is to use either bracket notation with quotes or dot notation with correct formatting.
