Jint

JavaScriptEngineSwitcher.Jint contains a JintJsEngine adapter (wrapper for the Jint version 4.15.3).

Engine settings

You can specify a settings of JS engine during its registration:

engineSwitcher.EngineFactories.AddJint(newJintSettings{StrictMode=true});

If you manually create an instance of JS engine, then you can pass settings via the constructor:

IJsEngineengine=newJintJsEngine(newJintSettings{StrictMode=true});

Consider in detail properties of the JintSettings class:

Property name	Data type	Default value	Description
AllowReflection	Boolean	false	Flag for whether to allow the usage of reflection API in the script code. This affects Object.GetType, Exception.GetType, Exception.TargetSite and Delegate.Method.
CompileRegex	Nullable<Boolean>	false	Value that determines whether to create compiled instances of regular expressions during script pre-compilation: true - regular expression are compiled by using the RegexOptions.Compiled option false - interpreted .NET regular expression instances are created null - inherits from the base options of original JS engine
DebuggerBreakCallback	DebugEventHandler delegate	null	Debugger break callback.
DebuggerExceptionThrownCallback	ExceptionThrownEventHandler delegate	null	Debugger exception thrown callback.
DebuggerStatementHandlingMode	JsDebuggerStatementHandlingMode enumeration	Ignore	Handling mode for script debugger statements. Can take the following values: Ignore. No action will be taken when encountering a debugger statement. Clr. debugger statements will trigger debugging through the System.Diagnostics.Debugger class. Script. debugger statements will trigger a break in Jint's DebugHandler. See the DebuggerBreakCallback configuration property.
DebuggerStepCallback	DebugEventHandler	null	Debugger step callback.
DisableEval	Boolean	false	Flag for whether to disable calls of eval function with custom code and Function constructors taking function code as string.
EnableDebugging	Boolean	false	Flag for whether to enable debug mode.
LocalTimeZone	TimeZoneInfo	TimeZoneInfo.Local	Local time zone for the Date objects in the script.
MaxArraySize	UInt32	UInt32.MaxValue	Maximum size for JavaScript array.
MaxJsonParseDepth	Int32	64	Maximum depth allowed when parsing JSON data using the JSON.parse static method.
MaxRecursionDepth	Int32	-1	Maximum allowed depth of recursion: -1 - recursion without limits; N - one scope function can be called no more than N times.
MaxStatements	Int32	0	Maximum number of statements.
MemoryLimit	Int64	0	Current memory limit for a engine in bytes.
RegexTimeoutInterval	Nullable<TimeSpan>	null	Timeout interval for regular expressions. If the value of this property is null, then the value of regular expression timeout interval are taken from the TimeoutInterval property.
RetainFunctionSourceText	Boolean	true	Flag for whether to retain the full source text of parsed functions. When this property is set to true, Function.prototype.toString() returns the original source; otherwise, toString() returns a function name() { [native code] } placeholder and the script source is not kept in memory.
StrictMode	Boolean	false	Flag for whether to allow run the script in strict mode.
TimeoutInterval	TimeSpan	TimeSpan.Zero	Interval to wait before the script execution times out.
