Works robustly in all environments, all versions.\n\nIn modern engines, `[...value]` or `Array.from(value)` or `for (const item of value) { }` are sufficient to iterate an iterable value (an object with a `Symbol.iterator` method). However, older engines:\n - may lack `Symbol`, array spread, or `for..of` support altogether\n - may have `Symbol.iterator` but not implement it on everything it should, like arguments objects\n - may have `Map` and `Set`, but a non-standard name for the iterator-producing method (`.iterator` or `['@@iterator']`, eg) and no syntax to support it\n - may be old versions of Firefox that produce values until they throw a StopIteration exception, rather than having iteration result objects\n - may be polyfilled/shimmed/shammed, with `es6-shim` or `core-js` or similar\n\nThis library attempts to provide an abstraction over all that complexity!\n\nIf called with a single value, it will return an array of the yielded values. If also called with a callback function, it will instead call that callback once for each yielded value.\n\nIn node v13+, `exports` is used by the `es-get-iterator` dependency to provide a lean implementation that lacks all the complexity described above, in combination with the `browser` field so that bundlers will pick up the proper implementation.\n\nIf you are targeting browsers that definitely all have Symbol support, then you can configure your bundler to replace `require('has-symbols')()` with a literal `true`, which should allow dead code elimination to reduce the size of the bundled code.\n\n## Example\n\n```js\nvar iterate = require('iterate-value');\nvar assert = require('assert');\n\nassert.deepEqual(iterate('a 💩'), ['a', ' ', '💩']);\nassert.deepEqual(iterate([1, 2]), [1, 2]);\nassert.deepEqual(iterate(new Set([1, 2])), [1, 2]);\nassert.deepEqual(iterate(new Map([[1, 2], [3, 4]])), [[1, 2], [3, 4]]);\n\nfunction assertWithCallback(iterable, expected) {\n\tvar values = [];\n\tvar callback = function (x) { values.push(x); };\n\titerate(iterable, callback);\n\tassert.deepEqual(values, expected);\n}\nassertWithCallback('a 💩', ['a', ' ', '💩']);\nassertWithCallback([1, 2], [1, 2]);\nassertWithCallback(new Set([1, 2]), [1, 2]);\nassertWithCallback(new Map([[1, 2], [3, 4]]), [[1, 2], [3, 4]]);\n```\n\n## Tests\nSimply clone the repo, `npm install`, and run `npm test`\n\n[package-url]: https://npmjs.org/package/iterate-value\n[npm-version-svg]: http://versionbadg.es/ljharb/iterate-value.svg\n[travis-svg]: https://travis-ci.org/ljharb/iterate-value.svg\n[travis-url]: https://travis-ci.org/ljharb/iterate-value\n[deps-svg]: https://david-dm.org/ljharb/iterate-value.svg\n[deps-url]: https://david-dm.org/ljharb/iterate-value\n[dev-deps-svg]: https://david-dm.org/ljharb/iterate-value/dev-status.svg\n[dev-deps-url]: https://david-dm.org/ljharb/iterate-value#info=devDependencies\n[npm-badge-png]: https://nodei.co/npm/iterate-value.png?downloads=true&stars=true\n[license-image]: http://img.shields.io/npm/l/iterate-value.svg\n[license-url]: LICENSE\n[downloads-image]: http://img.shields.io/npm/dm/iterate-value.svg\n[downloads-url]: http://npm-stat.com/charts.html?package=iterate-value" }
