Disallows the $.extend utility. Prefer Object.assign or the spread operator. Use the allowDeep option to allow using the method with the deep argument.

📋 This rule is enabled in plugin:no-jquery/all.

🔧 The --fix option on the command line can automatically fix some of the problems reported by this rule.
