Official documentation: Disable JavaScript With Chrome DevTools

There's now a command menu built into DevTools that makes it easier to disable JavaScript. This has been around as of April 2016 or so.

1. Open DevTools.
2. Press Command+Shift+P (Mac) or Control+Shift+P (Windows, Linux) to open the Command Menu. Make sure that your cursor's focus is on the DevTools window, not your browser viewport.
3. Type Disable JavaScript (or some version of that... it's a fuzzy search) and then press Enter.

Use the Enable JavaScript command when you want to turn it back on.

Click the gear icon in the corner of the Developer Tools, click Settings, then under Debugger, check Disable Javascript, as shown in the following video:
