The Learn Anything In 2 Weeks.

Dan dua strategi yang bisa lo terapin.

Disclaimer: Tulisan ini bukan tutorial yang mengajarkan back end programming tapi bagaimana proses gue belajar, memanfaatkan resources yang ada secara maksimal dan bertahan dalam melewati kebingungan. Pengalaman ini murni gue lakuin dalam 2 minggu tanpa di tambah — tambahin atau kurang — kurangin.

Pendahuluan

Gue anak kemarin sore yang baru banget belajar web back end programming dan walaupun zaman dulu (edan, padahal lulusnya belum lama) kuliahnya teknik informatika, setelah lulus gue lebih sering berurusan dengan web front end programming (masih anak kemarin sore) seperti html, css, javascript dan kawan — kawan framework (angular, vueJS). Gue hampir tidak pernah berurusan dengan Database…
