Bug: d.split("+").at is not a function. (In 'd.split("+").at(-1)', 'd.split("+").at' is undefined) error in safari 14.1 running react js about react

Looks like .at() is only supported in Safari 15.4 and above https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/at#browser_compatibility

Is this a React-specific issue or can it be fixed by a Polyfill?

[robinheinze]

I've traced this particular error to pdfjs-dist https://github.com/mozilla/pdfjs-dist/blob/5f07d5a4159bb99eee2f6143d1297f03b45bba58/lib/display/editor/tools.js#L140. So I don't think it's a React specific issue.

[pranavlotlikar]

How should I go about handling this issue as my React application is coming blank on some older version of Safari browser?
In the console, the above error is shown.

Pdf.js does not support Safari 14.1: https://github.com/mozilla/pdf.js/wiki/Frequently-Asked-Questions#legacy-build
This has nothing to do with React.
