Pengidentifikasi JavaScript

Identifier adalah nama yang diberikan kepada entitas seperti variabel, fungsi, kelas, dll

Aturan untuk Memberi Nama Pengidentifikasi JavaScript

Aturan untuk menulis identifier adalah

Nama pengidentifikasi harus dimulai dengan huruf, garis bawah const2, atau tanda dolar const3 Misalnya,
```
//valid
const a = 'hello';
const _a = 'hello';
const $a = 'hello';
```
Nama pengidentifikasi tidak boleh dimulai dengan angka. Misalnya,
```
//invalid
const 1a = 'hello'; // this gives an error
```
JavaScript peka terhadap huruf besar-kecil. Jadi y dan Y adalah pengenal yang berbeda. Misalnya,
```
const y = "hi";
const Y = 5;
console.log(y); // hi
console.log(Y); // 5
```
Kata kunci tidak dapat digunakan sebagai nama pengidentifikasi. Misalnya,
```
//invalid
const new = 5; // Error! new is a keyword.
```

Catatan. Meskipun Anda dapat memberi nama pengidentifikasi dengan cara apa pun yang Anda inginkan, sebaiknya berikan nama pengidentifikasi deskriptif

Jika Anda menggunakan pengidentifikasi untuk variabel untuk menyimpan jumlah siswa, lebih baik menggunakan siswa atau jumlah Siswa daripada x atau n

Catatan. Artikel ini didasarkan pada spesifikasi ECMAScript 5. Untuk versi ES2015 yang diperbarui, lihat Nama variabel JavaScript yang valid di ES2015

Literal nolnya adalah, sederhananya,

var ☃ = 'mr. jack'; // &#9731 and \u2603

2

Ada dua literal boolean.

var ☃ = 'mr. jack'; // &#9731 and \u2603

3 dan

Tak satu pun di atas diperbolehkan sebagai nama variabel

Kata-kata non-reserved yang bertindak seperti kata-kata yang dicadangkan

Properti

var ☃ = 'mr. jack'; // &#9731 and \u2603

var ☃ = 'mr. jack'; // &#9731 and \u2603

6, dan

var ☃ = 'mr. jack'; // &#9731 and \u2603

7 dari objek global adalah properti yang tidak dapat diubah atau hanya-baca di ES5. Jadi meskipun

var ☃ = 'mr. jack'; // &#9731 and \u2603

8 dalam lingkup global tidak akan menimbulkan kesalahan, itu tidak akan benar-benar melakukan apa pun. Untuk menghindari kebingungan, saya sarankan untuk menghindari penggunaan nama variabel ini

// In the global scope:
var NaN = 42;
console.log(NaN); // NaN

// …but elsewhere:
(function() {
	var NaN = 42;
	console.log(NaN); // 42
}());

Dalam mode ketat,

var ☃ = 'mr. jack'; // &#9731 and \u2603

9 dan

var ᐩ = 1; ᐩ++;

0 juga sebagai nama variabel. (Mereka bertindak seperti kata kunci dalam kasus itu. )

Spesifikasi ES3 lama mendefinisikan beberapa kata yang dicadangkan yang bukan lagi kata yang dicadangkan di ES5.

var ᐩ = 1; ᐩ++;

var ᐩ = 1; ᐩ++;

6. Mungkin ide yang bagus untuk menghindari ini juga, untuk kompatibilitas mundur yang optimal

Nama pengenal yang valid

Seperti disebutkan sebelumnya, spesifikasi membedakan antara nama pengidentifikasi dan pengidentifikasi. Pengidentifikasi membentuk subset dari nama pengidentifikasi, karena pengidentifikasi memiliki batasan tambahan yang tidak diperbolehkan. Misalnya,

perl -Mutf8 -e 'my $π = 3.14; print $π;'

2 adalah nama pengidentifikasi yang valid, tetapi pengidentifikasinya tidak valid

Jadi, apa yang diperbolehkan dalam nama pengidentifikasi?

Pengidentifikasi harus dimulai dengan

var ß = function() {
  return 'still in beta :)';
};

8,

var ß = function() {
  return 'still in beta :)';
};

9, atau karakter apa pun dalam kategori Unicode “Huruf besar (Lu)”, “Huruf kecil (Ll)”, “Huruf judul (Lt)”, “Huruf pengubah (Lm)”, “Lainnya

Sisa string dapat berisi karakter yang sama, ditambah karakter non-penggabung dengan lebar nol U+200C, karakter penggabung dengan lebar nol U+200D, dan karakter dalam kategori Unicode “Tanda tanpa spasi (Mn)”, “Penggabungan spasi

Itu dia, sungguh. Namun ada beberapa hal yang perlu diperhatikan…

Seperti yang Anda ketahui, JavaScript menggunakan UCS-2 secara internal, dan spesifikasinya mendefinisikan "karakter" sebagai berikut

Sepanjang sisa dokumen ini, frasa "unit kode" dan kata "karakter" akan digunakan untuk merujuk pada nilai 16-bit yang tidak ditandatangani yang digunakan untuk mewakili satu unit teks 16-bit.

Ini secara efektif berarti bahwa (mis. g.

var ﾠᅠᅟ= 'whitespace!!111';

_0, i. e. Ideograf Kompatibilitas U+2F800 CJK, yang tercantum dalam kategori [Lo]) tidak diizinkan dalam nama pengidentifikasi, karena JavaScript menginterpretasikannya sebagai dua bagian pengganti individu (mis. g.

var ﾠᅠᅟ= 'whitespace!!111';

_1) yang tidak cocok dengan salah satu kategori Unicode yang diizinkan

Gotcha lain adalah sebagai berikut

Untuk browser web, ada aturan ini, yaitu ketika kata-kata yang dicadangkan digunakan. Sebagian besar browser mendukung pengidentifikasi yang unescape ke kata yang dicadangkan, selama setidaknya satu karakter diloloskan menggunakan urutan pelolosan Unicode. Misalnya,

var ﾠᅠᅟ= 'whitespace!!111';

Validator nama variabel JavaScript

Bahkan jika Anda mempelajari aturan ini dengan hati, hampir tidak mungkin untuk menghafal setiap karakter dalam kategori Unicode berbeda yang diizinkan. Jika Anda meringkas semua aturan ini dalam satu ekspresi reguler khusus ASCII untuk JavaScript, panjangnya akan menjadi 11.236 karakter

Untuk alasan itu, saya membuat mothereff. in/js-variables, alat yang memudahkan Anda memeriksa apakah string yang diberikan adalah nama variabel yang valid dalam JavaScript

Jika nama variabel yang valid dimasukkan, alat akan memeriksa apakah browser yang Anda gunakan menangani pengidentifikasi dengan benar. Jika tidak, itu akan menampilkan peringatan, mendorong Anda untuk mengajukan bug browser

Validator akan memperingatkan Anda jika kata khusus ECMAScript 3 (yang bukan kata khusus lagi) dimasukkan. Coba, misalnya

Alat ini menggunakan Unicode 7. 0. basis data 0 karakter. Tentu saja, belum semua mesin JavaScript memiliki tingkat dukungan Unicode yang sama. Seperti yang dikatakan spek

Implementasi ECMAScript dapat mengenali karakter pengidentifikasi yang ditentukan dalam edisi selanjutnya dari Standar Unicode. Jika portabilitas menjadi perhatian, pemrogram sebaiknya hanya menggunakan karakter pengidentifikasi yang ditentukan dalam Unicode 3. 0

Untuk alasan ini, validator akan memperingatkan Anda jika nama variabel tidak valid saat Unicode 3. 0 basis data digunakan. Coba, misalnya

Bagi siapa pun yang penasaran, 'ಠ' diucapkan sebagai 'Ta' (bahasa Kannada). . )

Secara lebih deskriptif, ini adalah plosif palatal sub-apikal tanpa suara yang disedot. Jika Anda ingin mengeluarkan suara, posisikan lidah Anda seperti mencoba memasukkannya ke dalam tenggorokan. Bagian bawah lidah harus menyentuh bagian atas mulut Anda. Lalu, buat suara 'tuh'. Jika Anda melakukannya dengan benar, itu akan terdengar hampa dan 'lebih keras' daripada suara 't' bahasa Inggris normal

Sebaiknya tambahkan beberapa kata tentang nama properti yang valid, di ES5, sebenarnya tidak ada batasan dan kami dapat menggunakan kata kunci untuk mereka
