What it does
Allows you to set whether Brave will run the v8 JavaScript engine with more advanced JavaScript optimizations enabled. Disabling JavaScript optimizations (by setting this policy's value to 2) will mean that Brave may render web content more slowly. This policy can be overridden for specific URL patterns using the JavaScriptOptimizerAllowedForSites and JavaScriptOptimizerBlockedForSites policies. If this policy is left not set, JavaScript optimizations are enabled.
