Adding JavaScript ES6 to Dreamweaver CS6?

Question

How do I make it so that Dreamweaver CS6 doesn't give me a syntax error when I use `let` instead of `var`?

Answer 1

Dreamweaver CS6 was released in 2012, and does not have built-in support for the ES6 (ECMAScript **2015**) syntax, which includes the 'let' keyword.

However, you can still use ES6 syntax in Dreamweaver CS6 by configuring it to recognize the new syntax. Here are the steps you can follow:

1. Open Dreamweaver CS6 and go to "Edit" -> "Preferences" (or "Dreamweaver" -> "Preferences" on a Mac).
2. In the Preferences dialog box, select "Code Format" from the list on the left-hand side.
3. In the "Code Format" section, click the "Edit..." button next to the "File Extensions" field.
4. In the "Edit File Type" dialog box, select "JavaScript" from the list of file types.
5. In the "Edit JavaScript File Type" dialog box, click the "Advanced" tab.
6. In the "Advanced" tab, add "let" to the list of keywords under the "Reserved Words" section.
7. Click "OK" to close all of the dialog boxes.

After completing these steps, Dreamweaver CS6 should recognize 'let' as a valid keyword and stop giving you syntax errors. Keep in mind, though, that this method only adds support for the 'let' keyword, and does not provide full ES6 support.
