Laravel 5.4 - Write and use multiple scritps

I want to know where I should write my js files in Laravel 5.4 for compiling after this files.

Example:

I want to create a test.js file with a console.log('Hello World). Where I create this file ? Have I put it in the resources/assets/js/app.js folder ?

And other question I have is, if I want to load some differents scripts depending of the html view that I am using, how can I can configure them in the app.js for this ?

Example:

I have test1.js and test2.js. I want to load in the view1.html the test1.js and in the view2.html the test2.js. How could I do this ?

Thanks
