New features for developers in Chrome 83

 

 

Trusted types

Trusted types can help prevent various kinds of vulnerabilities i.e DOM-based cross-site scripting.

For example inner HTML

With trusted types turned on, if someone tries to pass a string, it will fail with a type error, because the browser doesn’t know if it can trust the string. Instead, its either need to pass in a trusted type or create the element and use append child.

Updates to Form controls

Use of HTML form controls are the key to the web’s interactivity. They are easy to use and familiar to users.  The styling of form controls can be inconsistent across browsers and operating systems and we frequently have to shift a number of CSS roles just to get a consistent look across devices.

The new form controls now available in Chrome 83
