An [[operator]] is symbol that performs a prescribed operation on one or more operands.

The [[dascript]] compiler recognizes the following operators:

== Remarks ==

Operators may be categorised based on the number of operands:

* Unary - one operand
* Binary - two operands
* Ternary - three operands

Operator precedence:

* TODO

Operator associativity:

* Left-associative operators are evaluated in order from left to right. Except for the assignment operators all binary operators are left-associative. For example, a + b - c is evaluated as (a + b) - c.
* Right-associative operators are evaluated in order from right to left. The assignment operators, and the conditional operator are right-associative. For example, x = y = z is evaluated as x = (y = z).
