// Consider these statements:
a = b
var x
(f())

// JavaScript will correctly infer semicolons and parse as:
a = b;
var x;
(f());

mdorr

var x
a = b
;(f()) // Note leading semicolon

// It will now parse correctly:
var x;
a = b;
(f());

// Method style - 'this' is the object that the method is being called on
object.method(parameters)
this = object

// Function style: this is the global, or window object 
method(parameters)
this = global/window

// Constructor style: this is the object that is being created by the constructor
instance = new Object(parameters)

If trying to pass a startup command with env substitution to the command/args fields in a kubernetes yml file, don't try to use substituition in the arguments as you normally would - that will be parsed differently. Instead, make your life easier by using /bin/sh -c like in this example:

command: ["/bin/sh"]
args: ["-c", "pg_dump -v -U ${DATABASE_USER} -h ${DATABASE_HOST} ${DATABASE_NAME} > /db-backup/$(date +'%Y-%m-%d_%H-%M-%S')_${DATABASE_NAME}.backup.sql"]
