Syntax

Average([selector])

Parameters

Return Value

Example

The following code example demonstrates how to use Average to calculate an average.

var fruits = [ "apple", "banana", "mango", "orange", "passionfruit", "grape" ];

var average = Enumerable.asEnumerable(fruits).Average(s => s.Length);

console.log("The average string length is " + average);

// This code produces the following output:
// The average string length is 6.5.
