Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The toSource() method returns a string representing the source code of the array.

Syntax

arr.toSource()

Return value

A string representing the source code of the array.

Description

The toSource method returns the following values:

  • For the built-in Array object, toSource returns the following string indicating that the source code is not available:
    function Array() {
        [native code]
    }
    
  • For instances of Array, toSource returns a string representing the source code.

This method is usually called internally by JavaScript and not explicitly in code. You can call toSource while debugging to examine the contents of an array.

Examples
