#Lodash core vs full code#

Babel is the industry standard for cross-compiling ES6+ code into ES5 compatible code for older browsers. There are more than 100 utility helpers and the majority of them aren't required anymore. cloneDeep is another utility that adds a significant amount of code. Why? It depends on itself, tools within its own library. get imports a significant amount of code. But lodash is stubborn, it's a painful library to reduce in file size. Transpilers, compilers and build tools try to solve the file size bundling issue in different ways, such as webpack using tree shaking to identify code that isn't used. Which brings us neatly to the topic of the blog - do we need lodash anymore?

Fortunately, we can rely on core js and babel, transpilers that spit out ES5 compatible JavaScript that IE11 through to IE Edge 18 can support. But that IE11 troll still lives in the cave over there, and we need to find a way to feed it, and avoid it.

We're now able to just do once, and it do it well. We don't have to tailor our JavaScript or CSS to the version of IE, or Safari, or Firefox, or even OS, because it's all a little difference. The three most used browsers in the world use Webkit or Chromium, standards are consistent and there's very little difference in adoption and behaviour across most browsers. Browsers are no longer competing on the same standard. Let's jump forward to today we're living in the days of ES11. Classes, functional programming, and all the goodness and richness that we take for granted was years away. In the world of Bootstrap, jQuery, underscore, prototype and a huge number of other tools, lodash provided a consistent and clear interface. I'm talking of course about Internet Explorer 11.Īt the time lodash was created, ES6 was just a glimmer in the eye of web developers, an idea and a desire for most front end developers. Lodash is one of those handful of libraries, that were created to solve a growing problem, that fortunately due to Microsoft's foresight, no longer exists. Some of the tools are driven by simplicity, some driven by configurability, and others by extensibility. In today's world of JavaScript, there's a huge number of tools that solve the same problem in slightly differing ways.
