Step 1 / 14

A trie stores words letter by letter, so words that share a prefix share a path. A star (*) marks the end of a word.

JavaScript

1class Trie {
2  constructor() { this.root = { children: {}, end: false }; }
3  insert(word) {
4    let node = this.root;
5    for (const ch of word) {
6      node = node.children[ch] ??= { children: {}, end: false };
7    }
8    node.end = true;
9  }
10  suggest(prefix) {
11    let node = this.root;
12    for (const ch of prefix) {
13      node = node.children[ch];
14      if (!node) return [];
15    }
16    return collect(node, prefix); // every node with end: true is a word
17  }
18}

Tip: use the arrow keys to step and the space bar to play or pause.
