# @total-typescript/ts-reset

## 0.6.1

### Patch Changes

- 757be40: Fixed a bug where creating an empty map would no longer infer types correctly.

## 0.6.0

### Minor Changes

- 6574858: Added a rule, `/map-constructor`, to default `Map` to `Map<unknown, unknown>` when no arguments are passed to the constructor.

  Before, you'd get `any` for both key and value types. Now, the result of `Map.get` is `unknown` instead of `any`:

  ```ts
  const userMap = new Map();

  const value = userMap.get("matt"); // value: unknown
  ```

  This now is part of the recommended rules.

- 5bf3a15: Added a rule, `/promise-catch`, to change the `catch` method to take `unknown` instead of `any` as an argument.

  ```ts
  const promise = Promise.reject("error");

  // BEFORE

  promise.catch((error) => {
    console.error(error); // error is any!
  });

  // AFTER

  promise.catch((error) => {
    console.error(error); // error is unknown!
  });
  ```

  Fixed a bug where running .filter on a union of arrays would not work.

## 0.5.1

### Patch Changes

- Added homepage for npm purposes.

## 0.5.0

### Minor Changes

- 49b8603: Added a rule, `/session`, to make sessionStorage and localStorage safer.

  ```ts
  // Is now typed as `unknown`, not `any`!
  localStorage.a;

  // Is now typed as `unknown`, not `any`!
  sessionStorage.abc;
  ```

- 49b8603: Added a `/dom` entrypoint to allow users to import DOM-only rules.

## 0.4.1

### Patch Changes

- No changes, just pushing to fix the previous slightly borked release.

## 0.4.0

### Minor Changes

- ce9db42: Added support for widening in `Array.lastIndexOf`, `Array.indexOf`, `ReadonlyArray.lastIndexOf` and `ReadonlyArray.indexOf`.
- 107dfc2: Changed the array.includes on readonly arrays to NOT be a type predicate. Before this change, this perfectly valid code would not behave correctly.

  ```ts
  type Code = 0 | 1 | 2;
  type SpecificCode = 0 | 1;

  const currentCode: Code = 0;

  // Create an empty list of subset type
  const specificCodeList: ReadonlyArray<SpecificCode> = [];

  // This will be false, since 0 is not in []
  if (specificCodeList.includes(currentCode)) {
    currentCode; // -> SpecificCode
  } else {
    // This branch will be entered, and ts will think z is 2, when it is actually 0
    currentCode; // -> 2
  }
  ```

  Removing the type predicate brings ts-reset closer towards correctness.

  Added the `Map.has` rule.

  Similar to `.includes` or `Set.has()`, `Map.has()` doesn't let you pass members that don't exist in the map's keys:

  ```ts
  // BEFORE
  const userMap = new Map([
    ["matt", 0],
    ["sofia", 1],
    [2, "waqas"],
  ] as const);

  // Argument of type '"bryan"' is not assignable to
  // parameter of type '"matt" | "sofia" | "waqas"'.
  userMap.has("bryan");
  ```

  With the rule enabled, `Map` follows the same semantics as `Set`.

  ```ts
  // AFTER
  import "@total-typescript/ts-reset/map-has";

  const userMap = new Map([
    ["matt", 0],
    ["sofia", 1],
    [2, "waqas"],
  ] as const);

  // .has now takes a string as the argument!
  userMap.has("bryan");
  ```

### Patch Changes

- b15aaa4: Fixed an oversight with the initial `set-has` implementation by adding support to `ReadonlySet`.

## 0.3.3

### Patch Changes

- Fixed a bug where 0n was not being filtered out by filter-boolean
