Problem Statement

Create a function/use an in-built function, to compute the   dot product,   also known as the   scalar product   of two vectors. If possible, make the vectors of arbitrary length.

As an example, compute the dot product of the vectors:

If implementing the dot product of two vectors directly:

Let's start with the solution:

Step by Step solution about How to resolve the algorithm Dot product step by step in the Jsish programming language

Source code in the jsish programming language

/* Dot product, in Jsish */
function dot_product(ary1, ary2) {
    if (ary1.length != ary2.length) throw "can't find dot product: arrays have different lengths";
    var dotprod = 0;
    for (var i = 0; i < ary1.length; i++) dotprod += ary1[i] * ary2[i];
    return dotprod;
}

;dot_product([1,3,-5],[4,-2,-1]);
;//dot_product([1,3,-5],[4,-2,-1,0]);

/*
