Software\Policies\Microsoft\Edge\JavaScriptJitAllowedForSites Description
Allows you to set a list of site URL patterns that specify sites that are allowed to run JavaScript with JIT (Just In Time) compiler enabled. For detailed information on valid site URL patterns, see https://go.microsoft.com/fwlink/?linkid=2095322. Wildcards, *, are allowed. JavaScript JIT policy exceptions will only be enforced at a site granularity (eTLD+1). A policy set for only subdomain.contoso.com won't correctly apply to contoso.com or subdomain.contoso.com since they both resolve to the same eTLD+1 (contoso.com) for which there's no policy. In this case, policy must be set on contoso.com to apply correctly for both contoso.com and subdomain.contoso.com. This policy applies on a frame-by-frame basis and not based on top-level origin URL alone; so, for example, if contoso.com is listed in the JavaScriptJitAllowedForSites policy but contoso.com loads a frame containing fabrikam.com then contoso.com will have JavaScript JIT enabled, but fabrikam.com will use the policy from 'DefaultJavaScriptJitSetting' (Control use of JavaScript JIT), if set, or default to JavaScript JIT enabled. If you don't configure this policy for a site then the policy from 'DefaultJavaScriptJitSetting' applies to the site, if set, otherwise Javascript JIT is enabled for the site.
