Web/JavaScript/Reference/Global objects/TypedArray/toString

The toString() method returns a string representing the specified array and its elements. This method has the same algorithm as Array.prototype.toString(). TypedArray is one of the typed array types here.

Syntax

typedarray.toString()

Return value

A string representing the elements of the typed array.

Examples

The TypedArray objects override the toString method of Object. For TypedArray objects, the toString method joins the array and returns one string containing each typed array element separated by commas. For example, the following code creates a typed array and uses toString to convert the array to a string.

var numbers = new Uint8Array([2, 5, 8, 1, 4])
numbers.toString(); // "2,5,8,1,4"

JavaScript calls the toString method automatically when a typed array is to be represented as a text value or when an array is referred to in a string concatenation.

Compatibility

If a browser doesn't support the TypedArray.prototype.toString() method yet, JavaScript will call the toString method of Object:

var numbers = new Uint8Array([2, 5, 8, 1, 4])
numbers.toString(); // "[object Uint8Array]"
