Via Remote Import

🎯 Supported Target

• Deno

1. Import at the script via:
   • Deno Land

     import ... from "https://deno.land/x/range_iterator[@${Tag}]/mod.ts";

   • GitHub Raw (Require Tag)

     import ... from "https://raw.githubusercontent.com/hugoalh-studio/range-iterator-es/${Tag}/mod.ts";

ℹ️ Note

• Although it is recommended to import the entire module with the main path mod.ts, it is also able to import part of the module with sub path if available, but do not import if:

  • it’s file path has an underscore prefix (e.g.: _foo.ts, _util/bar.ts), or
  • it is a benchmark or test file (e.g.: foo.bench.ts, foo.test.ts), or
  • it’s symbol has an underscore prefix (e.g.: export function _baz() {}).

  These elements are not considered part of the public API, thus no stability is guaranteed for them.

• Although there have 3rd party services which provide enhanced, equal, or similar methods/ways to remote import the module, beware these services maybe inject unrelated elements and thus affect the security.

• It is recommended to import the module with tag for immutability.

🧩 API

• function rangeIterator(start: bigint, end: bigint, options?: RangeIteratorOptions<bigint>): Generator<bigint>;
  function rangeIterator(start: number, end: number, options?: RangeIteratorOptions<number>): Generator<number>;
  function rangeIterator(start: string, end: string, options?: RangeIteratorOptions<string>): Generator<string>;
  function rangeIterator(start: bigint, end: bigint, step: RangeIteratorIndexType<bigint>): Generator<bigint>;
  function rangeIterator(start: number, end: number, step: RangeIteratorIndexType<number>): Generator<number>;
  function rangeIterator(start: string, end: string, step: RangeIteratorIndexType<string>): Generator<string>;

• interface RangeIteratorOptions<T extends RangeIteratorAcceptType> {
    /**
     * Whether to exclusive end.
     * @default false
     */
    endExclusive?: boolean;
    /**
     * Step of the decrement/increment of the iterate.
     * @default 1n // Big integer.
     * @default 1 // Number/String.
     */
    step?: RangeIteratorIndexType<T>;
  }

• type RangeIteratorAcceptType = bigint | number | string;

• type RangeIteratorIndexType<T extends RangeIteratorAcceptType> = T extends bigint ? bigint : number;

✍️ Example

• Array.from(rangeIterator(1, 9));
  //=> [1, 2, 3, 4, 5, 6, 7, 8, 9]

• Array.from(rangeIterator(1n, 9n, { endExclusive: true }));
  //=> [1n, 2n, 3n, 4n, 5n, 6n, 7n, 8n]

• Array.from(rangeIterator(1, 9, { step: 0.5 }));
  //=> [1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9]

• Array.from(rangeIterator("a", "z"));
  //=> ["a", "b", "c", ... +20 ..., "x", "y", "z"]

• Array.from(rangeIterator(9, 1));
  //=> [9, 8, 7, 6, 5, 4, 3, 2, 1]

• Array.from(rangeIterator(9n, 1n, { endExclusive: true }));
  //=> [9n, 8n, 7n, 6n, 5n, 4n, 3n, 2n]

• Array.from(rangeIterator(9, 1, { step: 0.5 }));
  //=> [9, 8.5, 8, 7.5, 7, 6.5, 6, 5.5, 5, 4.5, 4, 3.5, 3, 2.5, 2, 1.5, 1]

• Array.from(rangeIterator("z", "a"));
  //=> ["z", "y", "x", ... +20 ..., "c", "b", "a"]
