The Daily WTF

Today, we have the special true confession from Bruce, who wrote some bad code, but at least knows it’s bad.

Bruce is a C# developer. Bruce is not a web developer. Someone around the office, though, had read an article about how TypeScript was closer to “real” languages, like C#, and asked Bruce to do some TypeScript work.

Now, in C# parlance, your key/value pair data-structure is called a Dictionary. So, when Bruce got stuck on how to store key/value pairs in TypeScript, he googled “typescript dictionary”, and got no useful results.

Disappointed, Bruce set out to remedy this absence:

export class KeyValuePair<TKey,TValue> { Key: TKey; Value: TValue; constructor (key: TKey, value: TValue) { this.Key = key; this.Value = value; } } export class Dictionary<TKey, TValue>{ private Collection: Array<KeyValuePair<TKey, TValue>> private IndexMap: Map<TKey, number> private index: number; public tryAdd(key: TKey, value: TValue): boolean { if (this.containsKey(key)) { return false;
