Investigate upgrade to the latest underscorejs/create POC

[mmansoor-magento]

Overview

For the underscorejs library we need to identify the following additional details:

• If this library is used on Admin UI or Storefront Luma or both
• What exact functionality is using this particular library
• What is a preliminary scope of work to migrate to the new version.
• Is it possible to migrate without introducing BIC into Luma
• Level of the impact of updating dependency in terms of BIC
• Create POC

Investigation Outcome

A complete report of affected areas, ways to migrate code, and level of BIC caused by migration.

current used 1.8.2
https://github.com/magento/magento2/blob/2.4-develop/lib/web/underscore.js
latest 1.13.1

version 1.13.0

Adds experimental support for native ESM imports in Node.js. You can now also do named imports or even deep module imports directly from a Node.js process in Node.js version 12 and later. Monolithic imports are recommended for use in production. State (such as mixed-in functions) is shared between CommonJS and ESM consumers.
Renames the UMD bundle to underscore-umd.js for consistency with the other bundle names. An alias named underscore.js is retained for backwards compatibility.
Restores an optimization in _.debounce that was unintentionally lost in version 1.9.0.
Various test and documentation enhancements.

version 1.12.0
Adds the _.get and _.toPath functions. The latter can be overridden in order to customize the interpretation of deep property paths throughout Underscore. A future version of Underscore-contrib will be providing a ready-made function for this purpose; users will be able to opt in to string-based path shorthands such as 'a.0.b' and 'a[0]["b"]' by using that function from Underscore-contrib to override _.toPath.
Fixes a bug in _.isEqual that caused typed arrays to compare equal when viewing different segments of the same underlying ArrayBuffer.
Improves the compatibility of _.isEqual, _.isDataView, _.isMap, _.isWeakMap and _.isSet with some older browsers, especially IE 11.
Significantly enhances the performance of _.isEmpty and several members of the isType family of functions.
Speeds up _.isEqual comparison of typed arrays and DataViews with idential buffer, byteOffset and byteLength.
Restores cross-browser testing during continuous integration to its former glory and adds documentation about engine compatibility.
Slims down the development dependencies for testing.
