a & b

The operands are converted to 32-bit integers and expressed by a series of bits (zeroes and ones). Numbers with more than 32 bits get their most significant bits discarded. For example, the following integer with more than 32 bits will be converted to a 32-bit integer:

Before: 11100110111110100000000000000110000000000001
After:              10100000000000000110000000000001

Each bit in the first operand is paired with the corresponding bit in the second operand: first bit to first bit, second bit to second bit, and so on.

Operator di dalam JavaScript - Halo teman-teman semuanya, pada kesempatan kali ini kita semua akan belajar tentang operator di dalam bahasa pemrogramman JavaScript.

Apa itu Operator?

Mari kita ambil ungkapan sederhana

a + b = 43
a - b = 23
a / b = 3.3
a % b = 3
a + b + c = 43Test
++a = 35
--b = 8
Set the variables to different values and then try...

a + b = 43
a - b = 23
a / b = 3.3
a % b = 3
a + b + c = 43Test
++a = 35
--b = 8
Set the variables to different values and then try...

Contoh Kode berikut menunjukkan cara menggunakan operator perbandingan dalam JavaScript.

<html>
   <body>  
      <script type = "text/javascript">
            var a = 10;
            var b = 20;
            var linebreak = "<br />";
      
            document.write("(a == b) => ");
            result = (a == b);
            document.write(result);
            document.write(linebreak);
         
            document.write("(a < b) => ");
            result = (a < b);
            document.write(result);
            document.write(linebreak);
         
            document.write("(a > b) => ");
            result = (a > b);
            document.write(result);
            document.write(linebreak);
         
            document.write("(a != b) => ");
            result = (a != b);
            document.write(result);
            document.write(linebreak);
         
            document.write("(a >= b) => ");
            result = (a >= b);
            document.write(result);
            document.write(linebreak);
         
            document.write("(a <= b) => ");
            result = (a <= b);
            document.write(result);
            document.write(linebreak);
      </script>      
      Set the variables to different values and different operators and then try...
   </body>
</html>

Kurang lebih hasilnya seperti berikut ini :

(a == b) => false 
(a < b) => true 
(a > b) => false 
(a != b) => true 
(a >= b) => false 
a <= b) => true
Set the variables to different values and different operators and then try...

(a | b) => 3 
(a ^ b) => 1

(a << b) => 16

3 - Membalikkan keadaan logis operannya. Jika suatu kondisi benar, maka operator Logical NOT akan membuatnya salah. Contoh:

(a & b) => 2 
(a | b) => 3 
(a ^ b) => 1 
(~b) => -4 
(a << b) => 16 
(a >> b) => 0
Set the variables to different values and different operators and then try...

4 salah.

Contoh Coba kode berikut untuk mempelajari cara menerapkan Operator Logis dalam JavaScript.

<html>
   <body>   
      <script type = "text/javascript">
            var a = true;
            var b = false;
            var linebreak = "<br />";
      
            document.write("(a && b) => ");
            result = (a && b);
            document.write(result);
            document.write(linebreak);
         
            document.write("(a || b) => ");
            result = (a || b);
            document.write(result);
            document.write(linebreak);
         
            document.write("!(a && b) => ");
            result = (!(a && b));
            document.write(result);
            document.write(linebreak);
      </script>      
      <p>Set the variables to different values and different operators and then try...</p>
   </body>
</html>

Kurang lebih hasilnya seperti berikut ini :

(a && b) => false 
(a || b) => true 
!(a && b) => true
Set the variables to different values and different operators and then try...

1 - Ini memindahkan semua bit dalam operan pertamanya ke kiri dengan jumlah tempat yang ditentukan dalam operan kedua. Bit baru diisi dengan nol. Menggeser nilai yang ditinggalkan oleh satu posisi sama dengan mengalikannya dengan 2, menggeser dua posisi sama dengan mengalikan dengan 4, dan seterusnya. Misalnya:

Value of a => (a = b) => 10
Value of a => (a += b) => 20 
Value of a => (a -= b) => 10 
Value of a => (a *= b) => 100 
Value of a => (a /= b) => 10

(Right Shift) - Operator Pergeseran Kanan Biner. Nilai operan kiri digerakkan ke kanan dengan jumlah bit yang ditentukan oleh operan kanan. Misalnya: (A >> 1) adalah 1.

Value of a => (a += b) => 20 
Value of a => (a -= b) => 10 
Value of a => (a *= b) => 100 
Value of a => (a /= b) => 10
Value of a => (a %= b) => 0
Set the variables to different values and different operators and then try...

a / b = 3.3
a % b = 3
a + b + c = 43Test
++a = 35
--b = 8

Operator Bersyarat (? :)

Operator bersyarat pertama mengevaluasi ekspresi untuk nilai benar atau salah dan kemudian mengeksekusi salah satu dari dua pernyataan yang diberikan tergantung pada hasil evaluasi.

a - b = 23
a / b = 3.3
a % b = 3
a + b + c = 43Test
++a = 35
--b = 8
Set the variables to different values and then try...

typeof Operator

The typeof operator adalah operator unary yang ditempatkan sebelum operan tunggal, yang dapat dari jenis apa pun. Nilainya adalah string yang menunjukkan tipe data operan.

The typeof mengevaluasi operator untuk "nomor", "string", atau "boolean" jika operan adalah sebuah angka, string, atau nilai boolean dan kembali benar atau salah berdasarkan evaluasi.

Kapan Operator bitwise digunakan?

Bitwise merupakan operator khusus yang bisa digunakan untuk menangani operasi logika bilangan biner dalam bentuk bit.

Operator Bitwise apa saja?

6 Macam Operator Bitwise.

Operator Bitwise | (OR) ... .

Operator Bitwise & (AND) ... .

Operator Bitwise ^ (Exclusive OR / XOR) ... .

Operator Bitwise ~ (NOT) ... .

Operator Bitwise >> (Shift Right) ... .

Operator Bitwise << (Shift Left).

Apa fungsi operator bitwise?

Bitwise adalah operator khusus untuk menangani operasi logika bilangan biner dalam bentuk bit. Bilangan biner sendiri merupakan jenis bilangan yang hanya terdiri dari 2 jenis angka, yakni 0 dan 1. Jika nilai asal yang dipakai bukan bilangan biner, akan dikonversi secara otomatis oleh compiler C menjadi bilangan biner.

Bagaimana cara kita melakukan sebuah operasi perkalian pada JavaScript?

Untuk melakukan operasi perkalian, kita menggunakan simbol asterik * . Jangan gunakan x , karena simbol x bukan termasuk dalam operator di dalam pemrograman. Lalu untuk pemangkatan kita menggunakan asterik ganda ** . Untuk pembagian, kita gunakan simbol garis miring / .
