Jint

JavaScriptEngineSwitcher.Jint contains a JintJsEngine adapter (wrapper for the Jint version 4.4.0).

Engine settings

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

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

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

IJsEngine engine = new JintJsEngine(
    new JintSettings
    {
        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`.
`DebuggerBreakCallback`	`DebugEventHandler` delegate	`null`	Debugger break 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.
`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.
