The <discard> SVG element may be used to specify the time at which a particular element should be removed from the DOM. This allows an SVG viewer to conserve memory by discarding elements that are no longer needed, such as animated elements that have completed.

Private properties are counterparts of the regular class properties which are public, including class fields, class methods, etc. Private properties get created by using a hash # prefix and cannot be legally referenced outside of the class. The privacy encapsulation of these class properties is enforced by JavaScript itself. The only way to access a private property is via dot notation, and you can only do so within the class that defines the private property.

JavaScript applications consist of statements with an appropriate syntax. A single statement may span multiple lines. Multiple statements may occur on a single line if each statement is separated by a semicolon. This isn't a keyword, but a group of keywords.

An empty statement is used to provide no statement, although the JavaScript syntax would expect one.

The for statement creates a loop that consists of three optional expressions, enclosed in parentheses and separated by semicolons, followed by a statement (usually a block statement) to be executed in the loop.

The function* declaration creates a binding of a new generator function to a given name. A generator function can be exited and later re-entered, with its context (variable bindings) saved across re-entrances.
