Accessing Property Of Object With Variable

If I have an object, with properties like name, phone_number, etc...how can I access those in Javascript with a variable? I want to access the property name in javascript by doing

Solution 1:

object[propertiesArray[0]]

You can just use object[propertiesArray[0]].

Solution 3:

Try

object[propertiesArray[0]];
