For crash courses, this channel is awesome and must watch. Soo nice explanation and to the point!

BTW the reason why you may want to combine improt/require is because some required libraries may not support ES6 and you are stuck. Is handy to have the felxibility to have both, specially if you are mirating old projects.

[paulthomas]

Time to put BUN in my resume!, thanks ❤

[Salah-YT]

thank you so much Brad it is an amazing video about Bun 🙂

[odebroqueville]

Very nice quick overview of what we can do with bun. Thank you, Brad. Just wondering, couldn't you have used fetch() instead of axios?

[youneshenni]

Bun is such a good addition to the js ecosystem.

[Abdulhannan.m]

Excellent Brad. But there is no need to put await before Bun.file function as per the offical docs.

Code should be like this

const file = Bun.file("cv.txt");
console.log(await file.text());
console.log(file.stream());
console.log(await file.arrayBuffer());
