@adidahiya what needs to be done for Classes.iconClass(...) to work for these new icons?

[adidahiya]

@nrathi nothing, Classes.iconClass(iconName: string | undefined) accepts a string, rather than an enum

[nrathi]

Ah, it's not working for me :/. It seems like "bp3-icon-numeric" inserts content ::before, but "bp3-icon-array-numeric" doesn't.

Oh nevermind, icon fonts were deprecated her https://blueprintjs.com/docs/#core/components/icon.css.

[adidahiya]

Ah sorry, yeah... the icon font is deprecated, you should use the React components. I'll go ahead and add /** @deprecated */ for more clarity.
