    API

    Returns an array of callsite objects with the following methods:

    • getThis: Returns the value of this.
    • getTypeName: Returns the type of this as a string. This is the name of the function stored in the constructor field of this, if available, otherwise the object's [[Class]] internal property.
    • getFunction: Returns the current function.
    • getFunctionName: Returns the name of the current function, typically its name property. If a name property is not available an attempt will be made to try to infer a name from the function's context.
    • getMethodName: Returns the name of the property of this or one of its prototypes that holds the current function.
    • getFileName: If this function was defined in a script returns the name of the script.
    • getLineNumber: If this function was defined in a script returns the current line number.
    • getColumnNumber: If this function was defined in a script returns the current column number
    • getEvalOrigin: If this function was created using a call to eval returns a string representing the location where eval was called.
    • isToplevel: Is this a top-level invocation, that is, is this the global object?
    • isEval: Does this call take place in code defined by a call to eval?
    • isNative: Is this call in native V8 code?
    • isConstructor: Is this a constructor call?
