javascript运算符

Use the assignment operator = to assign a value to a variable:

使用赋值运算符=为变量赋值：

const a = 2let b = 2var c = 2

This operator has several shortcuts for all the arithmetic operators which let you assign to the first operand the result of the operations with the second operand.

该运算符为所有算术运算符提供了几种快捷方式，您可以将第二个操作数的运算结果分配给第一个操作数。

They are:

他们是：

• +=: addition assignment

  += ：附加分配

• -=: subtraction assignment

  -= ：减法分配

• *=: multiplication assignment

  *= ：乘法分配

• /=: division assignment

  /= ：部门分配

• %=: remainder assignment

  %= ：剩余分配

• **=: exponentiation assignment

  **= ：求幂分配

Examples:

例子：

let a = 0a += 5 //a === 5a -= 2 //a === 3a *= 2 //a === 6a /= 2 //a === 3a %= 2 //a === 1

To be clear, the above operations are executed one after another, so a at the end is 1, not 0

需要明确的是，上面的操作被执行的一个接一个，所以a在端部为1，而不是0
