However, when you are targeting modern browsers, you may find out that there are many methods which are already supported natively thanks to ECMAScript5 [ES5] and ECMAScript2015 [ES6]. If you want your project to require fewer dependencies, and you know your target browser clearly, then you may not need Lodash\u002FUnderscore.\n\nYou are welcome to contribute with more items provided below.\n\n* If you are targeting legacy JavaScript engine with those ES5 methods, you can use [es5-shim](https:\u002F\u002Fgithub.com\u002Fes-shims\u002Fes5-shim)\n\n* Please note that, the examples used below are just showing you the native alternative of performing certain tasks. For some functions, Lodash provides you more options than native built-ins. This list is not a 1:1 comparison.\n\n* Please send a PR if you want to add or modify the code. No need to open an issue unless it's something big and you want to discuss.\n\n\n## Voice of Developers\n\n> [Make use of native JavaScript object and array utilities before going big.](https:\u002F\u002Ftwitter.com\u002Fcodylindley\u002Fstatus\u002F692356631007342593)\n\n> —\u003Ccite>Cody Lindley, Author of [jQuery Cookbook](http:\u002F\u002Fshop.oreilly.com\u002Fproduct\u002F9780596159788.do) and [JavaScript Enlightenment](http:\u002F\u002Fshop.oreilly.com\u002Fproduct\u002F0636920027713.do)\u003C\u002Fcite>\n\n\u003C!-- -->\n> [You probably don't need Lodash.
