This article mainly introduces the relevant knowledge of "what are WeChat Mini Programs's basic operators". The editor shows you the operation process through an actual case, and the operation method is simple, fast and practical. I hope this article "what are WeChat Mini Programs's basic operators" can help you solve the problem.

Basic operator

Sample code:

Var a = 10, b = 20 bounding / addition operation console.log (30 = a + b); / / subtraction operation console.log (- 10 = a-b); / / multiplication operation console.log (= a * b); / / division operation console.log (= a / b); / / remainder operation console.log (10 = a% b)

The addition operation (+) can also be used as a concatenation of strings.

Var a ='.w', b = 'xs';// string concatenation console.log (' .wxs'= a + b); unary operator

Sample code:

Var a = 10, b = 20ramp / self-incrementing operation console.log (10 = + +); console.log (12 = + + a); / / self-subtractive operation console.log (12 = a Mustang -); console.log (10 =-a); / / positive operation console.log (10 = + a); / / negative operation console.log (0-10 =-a); / / No operation console.log (- 11 = ~ a); / take inverse operation console.log (false =! a) / / delete operation console.log (true = delete a.fake); / / void operation console.log (undefined = void a); / / typeof operation console.log ("number" = typeof a); bit operator

Sample code:

Var a = 10, b = 20 console.log / left shift console.log (80 = (a > 2)); / / signed right shift operation console.log (2 = (a > > 2)); / / and operation console.log (2 = (a & 3)); / / XOR operation console.log (9 = (a ^ 3)); / or operation console.log (11 = (a | 3)); comparison operator

Sample code:

Var a = 10, b = 20 / less than console.log (true = = (a)

B)); / / less than or equal to console.log (true = (a = b)); equivalent operator

Sample code:

Var a = 10, b = 20 console.log / equal sign console.log (false = (a = = b)); / / non-equal sign console.log (true = (a! = b)); / / congruent sign console.log (false = (a = b)); / / non-equal sign console.log (true = (a! = = b)); assignment operator

Sample code:

Var a = 10 + = 10 + + = 5 + console.log (- 1 = = a); a = 10 + = 11 + console.log (- 1 = a); a = 10 +-= 11 + console.log (- 1 = a); a = 10X a = 2boot console.log (2 = = a); a = 10X a = 2th console.log (2 = = a); a = 10X a > = 2th console.log (2 = = a) A = 10; a & = 3bot console.log (2 = a); a = 10; a ^ = 3x console.log (9 = a); a = 10; a | = 3bot console.log (11 = a); binary logic operator

Sample code:

Var a = 10, b = 20 console.log / console.log (20 = (a & b)); / / logic or console.log (10 = (a | | b)); other operators

Sample code:

Var a = 10, b = 20, the console.log / conditional operator (20 = = (a > = 10? A + 10: B + 10)); / / comma operator console.log (20 = (a, b)); operator precedence operator indicates associativity 20 (...) parentheses nmp A19. . ... Member access from left to right.
