Graphs in JavaScript
Practice this questionWANT TO UNDERSTAND THE CONCEPT FIRST?Learn Graphs in JavaScript
Graph representation
const graph = {
A: ['B', 'C'],
B: ['D'],
C: ['E'],
};Problems to practice
- Number of Islands
- BFS/DFS traversal
- Course Schedule
- Clone Graph
- Shortest Path in Unweighted Graph
- Topological Sort
Example: BFS
function bfs(graph, start) {
const visited = new Set([start]);
const queue = [start];
while (queue.length) {
const node = queue.shift();
console.log(node);
for (const neighbor of graph[node] || []) {
if (!visited.has(neighbor)) {
visited.add(neighbor);
queue.push(neighbor);
}
}
}
