We use Terraform because we needed a way to automate the process of building and deploying feature branches. We wanted to hide the complexity such that when a dev creates a PR, it triggers a build and deployment without the dev having to worry about any of the 'plumbing' going on behind the scenes. Terraform allows us to automate the process of provisioning DNS records, Amazon S3 buckets, Amazon EC2 instances and AWS Elastic Load Balancing (ELB)'s. It also makes it easy to tear it all down when finished. We also like that it supports multiple clouds, which is why we chose to use it over AWS CloudFormation.

I use Terraform because it hits the level of abstraction pocket of being high-level and flexible, and is agnostic to cloud platforms. Creating complex infrastructure components for a solution with a UI console is tedious to repeat. Using low-level APIs are usually specific to cloud platforms, and you still have to build your own tooling for deploying, state management, and destroying infrastructure.

However, Terraform is usually slower to implement new services compared to cloud-specific APIs. It's worth the trade-off though, especially if you're multi-cloud. I heard someone say, "We want to preference a cloud, not lock in to one." Terraform builds on that claim.

I use JavaScript these days and for few years I didn't have to use jQuery at all. I used to use it back in the days when IE8 and similar was a thing. But due to better browser support of native functions for DOM manipulation I could move to vanilla JavaScript. Most of the time, that's all I need to work with modals/accordions and similar. But I'm not saying that jQuery is bad. It was, and still is a great tool. Some of it's features are available in all browsers nowadays so it is not so important as it used to be. But jQuery has still advantage for example in it's selector engine, some DOM selections which are easy in jQuery are a bit more difficult in vanilla JS (you have to create some helper functions or use some 3rd party library to help you with that), but to be honest I needed this on very few occasions. So it really depends on your project (supported browses, plain JS or some bundling - gulp, Webpack, whether you plan to use modules etc.). Hope this helps.

Using Webpack is one of the best decision ever. I have used to Grunt and gulp previously, but the experience is not the same, and despite I know there are other bundlers like Parcel, Webpack gives me the perfect balance between automatization and configuration. The ecosystem of tools and loaders is amazing, and with WebPack #merge, you can modularize your build and define standard pieces to assemble different build configurations. I don't like processes where you cannot see their guts, and you have to trust in magic a little bit too much for my taste. But also I don't want to reinvent the wheel and lose too much time configuring my build processes. And of course, I love #WebPackDevServer and hot reloading.
