Disabling JavaScript optimizations (by setting this policy's value to 2) will mean that Microsoft Edge may render web content more slowly. This policy can be overridden for specific URL patterns using the 'JavaScriptOptimizerAllowedForSites' (Allow JavaScript optimization on these sites) and 'JavaScriptOptimizerBlockedForSites' (Block JavaScript optimizations on these sites) policies. If you don't configure this policy, JavaScript optimizations are enabled. Policy options mapping: * AllowJavaScriptOptimizer (1) = Enable advanced JavaScript optimizations on all sites * BlockJavaScriptOptimizer (2) = Disable advanced JavaScript optimizations on all sites Use the preceding information when configuring this policy.
