Lighthouse Issues And Legacy JavaScript In Codebase

Current Behavior

The Below Functions On Line 15 Of The CDN Delivered Version Of Ionicons Are Considered As Legacy Function And Should Be Updated Ideally ( Yes Its Version 7.1.0 )

• Array.prototype.fill
• Array.prototype.filter
• Array.prototype.find
• Array.prototype.findIndex
• Array.prototype.forEach
• Array.from
• Array.prototype.map
• Array.prototype.some
• Number.isInteger
• Number.isSafeInteger
• Object.entries
• Object.freeze
• Object.getOwnPropertyDescriptors
• Object.getPrototypeOf
• Object.isExtensible
• Object.isFrozen
• Object.isSealed
• Object.keys
• Object.preventExtensions
• Object.seal
• Object.values
• String.prototype.codePointAt
• String.fromCodePoint
• String.raw
• String.prototype.repeat

Expected Behavior

The Above Mentioned Methods Should Ideally Be In The More Modern Version Of Themselves So That We Can Potentially Save 23.0 KiB ( As Per Lighthouse ) On The Size Of The Package And It Should Result In Better Compatibility On Modern Browsers

For Example

Array.prototype.map Can Be Changes To Well array.map() And Much More

Steps to Reproduce

https://unpkg.com/ionicons@7.1.0/dist/ionicons/ionicons.esm.js https://unpkg.com/ionicons@7.1.0/dist/ionicons/ionicons.js

Just Import Them In A Good Enough HTML Page That Can Be Recognised By Lighthouse And Run The Test Then View The Performance Section For This Issue It Will Be Displayed There With Potential Suggestions As Well

Additional Information

They Are An Easy Fix They Require Changing Existing Legacy Methods To Their Modern Counterparts. For Your Information This Was Spotted Since Chrome Version 125.0.6422.60 ( 64Bit ). I Will Try To Look Into It If I Can And If Time Is Available
