In graph theory, the shortest path problem is finding a path between two vertices in a graph such that the sum of edge weights is minimized. To implement shortest path algorithms, we need to modify our graph structure to support weighted edges. Setting Up Weighted Graphs First, let's modify our graph methods to handle weights: class WeightedGraph { constructor() { this.nodes = []; this.edges = {}; } ...
