npm WARN deprecated [email protected]: Modern JS already guarantees Array#sort() is a stable sort, so this library is deprecated. See the compatibility table on MDN: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort#browser_compatibility
npm WARN deprecated [email protected]: flatten is deprecated in favor of utility frameworks such as lodash.

npm WARN deprecated [email protected]: This SVGO version is no longer supported. Upgrade to v2.x.x.

npm WARN deprecated [email protected]: core-js@<3.23.3 is no longer maintained and not recommended for usage due to the number of issues. Because of the V8 engine whims, feature detection in old core-js versions could cause a slowdown up to 100x even if nothing is polyfilled. Some versions have web compatibility issues. Please, upgrade your dependencies to the actual version of core-js.
