Optimization Passes

{{#include ../../links.md}}

[Script optimization] is performed via multiple passes. Each pass does a specific optimization.

The optimization is completed when no passes can simplify the [AST] any further.

Built-in Optimization Passes

Pass	Description
Dead code elimination	Eliminates code that cannot be reached
Constants propagation	Replaces [constants] with values
Compound assignments rewrite	Rewrites assignments into compound assignments
Eager operator evaluation	Eagerly calls operators with [constant] arguments
Eager function evaluation	Eagerly calls functions with [constant] arguments
