# How to integrate Batch's snippet (ECMAScript 6) using a Tag Manager?
Batch methods available in our [documentation](https://doc.batch.com/developer/sdk/web/profile-data) (for example to collect profile data) are written in the latest available version of JavaScript. However, some Tag Management Systems do not support ECMAScript 6.
## Managing compatibility issues
In some cases, Batch JavaScript tags are not supported by default by Tag managers like Google Tag Manager (GTM) and Tag Commander due to the use of arrow functions.
In order to use the preconfigured JavaScript tags in these Tag Managers, you must remove all the arrow functions it contains. This can be done easily by using a tool like [Babel](https://babeljs.io/repl/#?browsers=\&build=\&builtIns=false\&corejs=3.6\&spec=false\&loose=false\&code_lz=Q\&debug=false\&forceAllTransforms=false\&shippedProposals=false\&circleciRepo=\&evaluate=false\&fileSize=false\&timeTravel=false\&sourceType=script\&lineWrap=false\&presets=env\&prettier=false\&targets=\&version=7.15.8\&externalPlugins=\&assumptions=%7B%7D).
## Babel
You can use our [pre-configured Babel link](https://babeljs.io/repl/#?browsers=defaults%2C%20not%20ie%2011%2C%20not%20ie_mob%2011\&build=\&builtIns=false\&corejs=3.21\&spec=false\&loose=false\&code_lz=Q\&debug=false\&forceAllTransforms=false\&modules=false\&shippedProposals=false\&circleciRepo=\&evaluate=false\&fileSize=false\&timeTravel=false\&sourceType=module\&lineWrap=true\&presets=env%2Creact%2Cstage-2\&prettier=false\&targets=\&version=7.24.7\&externalPlugins=%40babel%2Fplugin-transform-arrow-functions%407.24.7\&assumptions=%7B%7D) to convert Batch tags into a JavaScript format compatible with Tag Management System tools.
{% hint style="warning" %}
Ensure that the plugin @babel/plugin-transform-arrow-functions is added in the bottom left corner of Babel.
