I have gulp file that is having issues with latest update to gulp 4 I am getting assertion errors (AssertionError [ERR_ASSERTION]: Task function must be specified) and it seems (from googling) to have to do with how tasks are defined, but not sure if this is the case here and what needs to change.

I have an ASP.NET Core website with TypeScript. My ASP.NET Core setup is typical in that it has a node_modules folder in the root of the project and then I copy the source folders of the libraries I'm using from node_modules to wwwroot/lib using Gulp.

I am using laravel 7. How can I use Babel with mix.combine ? I can find something in the docs but only mentions vue and react automatically using Babel? I am used tot Gulp and not Webpack. With Gulp I just use it for converting es6 to es5.
