Obtain smallest value from array in Javascript?

Array justPrices has values such as:

[0] = 1.5
[1] = 4.5
[2] = 9.9.

How do I return the smallest value in the array?

Solution

  • Jon Resig illustrated in this article how this could be achieved by extending the Array prototype and invoking the underlying Math.min method which unfortunately doesn't take an array but a variable number of arguments:

    Array.min = function( array ){
    return Math.min.apply( Math, array );
};

    and then:

    var minimum = Array.min(array);
