Operator unary plus (+_) mendahului operannya dan mengevaluasi ke operannya tetapi mencoba untuk , jika belum

Show

+x

Meskipun negasi unary (-_) juga dapat mengubah non-angka, unary plus adalah cara tercepat dan pilihan untuk mengubah sesuatu menjadi angka, karena tidak melakukan operasi lain pada angka. Itu dapat mengonversi representasi string bilangan bulat dan float, serta nilai non-string true, false, dan null. Bilangan bulat dalam format desimal dan heksadesimal (0x-awalan) didukung. Angka negatif didukung (meskipun tidak untuk hex). Menggunakan operator pada nilai BigInt melempar TypeError. Jika tidak dapat menguraikan nilai tertentu, itu akan dievaluasi menjadi NaN

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

Apa itu Operator?

Mari kita ambil ekspresi 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...
_4 sama dengan 
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...

0. JavaScript mendukung jenis operator berikut

  • Operator Aritmatika
  • Operator Perbandingan
  • Operator Logis (atau Relasional).
  • Operator Penugasan
  • Operator kondisional (atau ternary).

Kurang lebih hasilnya seperti berikut

(a < b) => true 
(a > b) => false 
(a != b) => true 
(a >= b) => false

    _1 - Jika salah satu dari dua operan tidak nol, maka kondisi menjadi benar. Sebagai 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...
    _2 benar
  • (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...
    _3 - Membalikkan keadaan logis dari operan. 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

jenis Operator

Operator typeof adalah operator unary yang ditempatkan sebelum operan tunggal, yang bisa bertipe apa saja. Nilainya adalah string yang menunjukkan tipe data operan

Operator typeof mengevaluasi ke "angka", "string", atau "boolean" jika operan adalah angka, string, atau nilai boolean dan mengembalikan benar atau salah berdasarkan evaluasi

Bagaimana cara membuat fungsi dalam JavaScript?

untuk membuat fungsi , penulisan harus didahului dengan sintaks " fungsi " lalu lanjutkan dengan nama fungsi yang ingin Anda buat . dan isi fungsi ditulis dalam kurung kurawal buka “{” dan kurung kurawal tutup “}”.

Bagaimana kita melakukan operasi perkalian dalam JavaScript?

Untuk melakukan operasi perkalian , kita menggunakan tanda bintang *. Jangan gunakan x , karena simbol x tidak termasuk dalam operator dalam pemrograman. Lalu untuk penahbisan kami menggunakan tanda bintang ganda **. Untuk pembagian, kita menggunakan tanda garis miring /.

Operator mana yang digunakan untuk memeriksa apakah dua nilai sama dan memiliki tipe yang sama?

6. Operator Identitas . Jika dua buah variabel merupakan objek yang sama atau memiliki nilai yang sama atau tidak. Jika sama dengan akan menghasilkan nilai BENAR dan sebaliknya, jika salah akan menghasilkan < /a> nilai SALAH.

Apa itu operator dalam JavaScript?

Operator adalah simbol yang dapat digunakan untuk memberi tahu mesin JavaScript untuk melakukan tindakan, operasi, atau melakukan perhitungan, baik itu perhitungan matematis atau logis . Nilai atau variabel yang diperlukan untuk melakukan operasi disebut operan.
