In this lab, you will learn how to create and use JavaScript Symbols. Symbols are a unique primitive data type that allow you to create non-string property keys. They can be used as identifiers for object properties, ensuring that the properties do not accidentally conflict with other properties.
Tasks:
- Create a symbol and store it in a variable named
symbolExample
. - Create an object called
myObject
and set a property key using the created symbol. - Create a function named
getOwnPropertySymbols
that takes an object as argument and returns an array containing the Symbol property keys of that object.
