A character escape represents a character that may not be able to be conveniently represented in its literal form.

The gradientTransform attribute contains the definition of an optional additional transformation from the gradient coordinate system onto the target coordinate system (i.e., userSpaceOnUse or objectBoundingBox). This allows for things such as skewing the gradient. This additional transformation matrix is post-multiplied to (i.e., inserted to the right of) any previously defined transformations, including the implicit transformation necessary to convert from object bounding box units to user space.

The k attribute specifies the amount for decreasing the spacing between the two glyphs in a kerning pair.

The id attribute assigns a unique name to an element.

The min attribute specifies the minimum value of the active animation duration.

A labeled statement is any statement that is prefixed with an identifier. You can jump to this label using a break or continue statement nested within the labeled statement.

The do...while statement creates a loop that executes a specified statement as long as the test condition evaluates to true. The condition is evaluated after executing the statement, resulting in the specified statement executing at least once.

The typeof operator returns a string indicating the type of the operand's value.

The const declaration declares block-scoped local variables. The value of a constant can't be changed through reassignment using the assignment operator, but if a constant is an object, its properties can be added, updated, or removed.
