Summary

Returns a string representing the source code of the function.

Method of Function
Implemented in JavaScript 1.1
ECMAScript Edition ECMAScript 1st Edition

Syntax

function.toString(indentation)

Parameters

indentation Non-standard
The amount of spaces to indent the string representation of the source code. If indentation is less than or equal to -1, most unnecessary spaces are removed.

Description

The Function object overrides the toString method inherited from Object; it does not inherit Object.prototype.toString. For Function objects, the toString method returns a string representation of the object in the form of a function declaration. That is, toString decompiles the function, and the string returned includes the function keyword, the argument list, curly braces, and the source of the function body.

JavaScript calls the toString method automatically when a Function is to be represented as a text value, e.g. when a function is concatenated with a string.
