Artinya, TypeScript membawa semua fitur bawaan JavaScript, tapi ditambah dengan fitur-fitur ekstra yang *powerful*.

Komputer harus menerjemahkan (*compile*) kode tersebut menjadi JavaScript standar terlebih dahulu, karena browser maupun Node.js cuma paham JavaScript biasa.\n\nKerennya lagi, karena sifatnya yang kompatibel ke belakang, kalian tetap bisa menuliskan kode JavaScript murni di dalam berkas TypeScript. Tapi ingat ya, hal ini nggak berlaku sebaliknya.\n\nFitur andalan TypeScript tentu saja adalah kemampuannya menambahkan tipe data (*type*) ke dalam JavaScript. Tipe data ini adalah properti wajib yang harus melekat pada setiap data yang kita definisikan.\n\nEntah itu pada variabel, fungsi, parameter, atau objek lainnya. Kalau nggak pakai fitur tipe data ini, kode TypeScript yang kalian tulis bakal balik lagi jadi JavaScript biasa.

Bahkan, ada Deno yang mendukung TypeScript secara bawaan (*native*) tanpa konfigurasi tambahan.\n\nMasih butuh alasan lain buat mencoba TypeScript? Berikut beberapa keuntungan menarik lainnya:\n\n* ***Self-documented code*** — Kehadiran tipe data di setiap variabel dan parameter fungsi secara otomatis mendokumentasikan maksud dari kode tersebut. Kita nggak perlu menebak-nebak tipe data apa yang harus dikirim ke sebuah fungsi.\n* **Deteksi error sejak dini** — Kode TypeScript wajib melewati proses kompilasi terlebih dahulu. Di fase inilah *compiler* bakal menyaring dan menunjukkan letak error agar bisa langsung kalian perbaiki sebelum aplikasi di-deploy. Selamat tinggal *runtime error*! 👋\n* **Dukungan *Functional Programming*** — Sama seperti JavaScript, TypeScript juga mendukung gaya pemrograman fungsional secara penuh.\n* **Pemrograman Berorientasi Objek (OOP) yang matang** — Konsep seperti *abstraction*, *encapsulation*, *inheritance*, dan *polymorphism* bisa kalian terapkan dengan rapi tanpa perlu trik atau *hack* aneh-aneh lagi.\n* **Memaksimalkan fitur Editor** — Ini bagian favorit saya. Fitur-fitur keren seperti *auto-completion*, sugerensi kode, *error checking*, dan *IntelliSense* bakal menyala maksimal di *code editor* kesayangan kalian.\n* ***Developer Experience* (DX) yang memuaskan** — Pengalaman menulis kode pakai TypeScript terasa jauh lebih menyenangkan. Kombinasi *IntelliSense* yang aktif dan jaminan kode yang lebih aman dari *runtime error* bikin proses koding jadi makin percaya diri.\n\n## Dari JavaScript ke TypeScript\n\nMari kita lihat contoh kasusnya. Kode JavaScript biasa kadang bisa membingungkan kalau dibaca pertama kali, terutama karena sifat dinamisnya. Apalagi kalau kita kurang teliti dalam menamai variabel atau fungsi—dan jujur saja, memberi nama yang pas itu memang sulit banget!\n\nCoba perhatikan cuplikan kode JavaScript di bawah ini:\n\n```javascript\nfunction add(a, b){\n    return a + b;\n}\n\nfunction fullName(firstName, lastName){\n    return firstName + \" \" + lastName;\n}\n```\n\nKita punya dua fungsi sederhana. Keduanya sama-sama menerima dua parameter, tapi tujuannya berbeda. Fungsi `add` dirancang buat menjumlahkan angka, sedangkan fungsi `fullName` dibuat buat menggabungkan nama depan dan belakang.\n\nSekarang, coba kita panggil kedua fungsi tersebut dengan cara yang agak 'ngawur':\n\n```javascript\nconsole.log(add(2, 4));                  \u002F\u002F output 6\nconsole.log(add(\"inva\", \"sikode\"));      \u002F\u002F output invasikode\nconsole.log(fullName(\"inva\", \"sikode\")); \u002F\u002F output inva sikode\nconsole.log(fullName(2, 4));             \u002F\u002F output 24\n```\n\nWalaupun kita memasukkan argumen yang salah target (`add(\"inva\", \"sikode\")` dan `fullName(2, 4)`), JavaScript nggak bakal protes dan tetap menjalankan kodenya karena secara sintaks memang dianggap valid.\n\nTapi perilaku seperti ini rawan memicu kekacauan logika di aplikasi kalian, terutama saat bekerja dengan tim besar.\n\nNah, TypeScript hadir buat menyelesaikan masalah ini dengan mendefinisikan jenis data apa saja yang boleh diterima oleh sebuah fungsi.\n\nSekarang mari kita ubah fungsi tadi menggunakan sintaks TypeScript:\n\n```typescript\nfunction add(a: number, b: number): number{\n    return a + b;\n}\n\nfunction fullName(firstName: string, lastName: string): string{\n    return firstName + \" \" + lastName;\n}\n```\n\nCukup dengan menambahkan keterangan tipe data dan mengubah ekstensi berkas dari `.js` menjadi `.ts`, fungsi kita sekarang sudah terproteksi dengan baik.\n\nJika kita mencoba memanggil fungsinya dengan parameter yang salah seperti sebelumnya:\n\n```typescript\nconsole.log(add(2, 4));                  \u002F\u002F output 6\nconsole.log(add(\"inva\", \"sikode\"));      \u002F\u002F error kompilasi!\nconsole.log(fullName(\"inva\", \"sikode\")); \u002F\u002F output inva sikode\nconsole.log(fullName(2, 4));             \u002F\u002F error kompilasi!\n```\n\nSaat kalian mencoba melakukan kompilasi, TypeScript bakal langsung menolak dan memunculkan pesan error. Bahkan, *code editor* seperti VS Code juga bakal langsung menandai baris yang salah dengan garis merah:\n\n```\nArgument of type 'string' is not assignable to parameter of type 'number'.\nArgument of type 'number' is not assignable to parameter of type 'string'.\n```\n\n> 📷 *Ilustrasi: peringatan galat tipe data di editor VS Code dengan garis bawah merah dan kotak pesan penjelasan error.*\n\nDengan begini, kita dipaksa buat menggunakan fungsi sesuai dengan aturan mainnya. Cara ini sangat efektif buat meminimalisir celah *bug* pada proyek yang kalian kembangkan.\n\nBagaimana? Tertarik buat mencoba TypeScript di proyek selanjutnya?
