LValue (Definition)

LValues are placed on the left of an assignment.

Availability:

ECMAScript edition - 2

An LValue is that expression or identifier reference that can be placed on the left hand side of an assignment.

An LValue must be a modifiable entity.

These are called Left-Hand-Side expressions in the ECMA standard.

The C language refers to these as Locator Values.
