# Assignment operators shorthand

JavaScriptreadability

JavaScript has many different assignment operators that are shorthand for longer versions. `+=`

is one of the more common ones. Most other calculations also have an assignment operator.

```
// regular assignment assigns the right value to the variable on the left
a = b
// we can shorten the code if the variable is itself part of the calculation
a = a + 5 // is the same as:
a += 5
// these are some of the available shorthand assignment operators
a += b // a = a + b addition assignment
a -= b // a = a - b subtraction assignment
a *= b // a = a * b multiplication assignment
a /= b // a = a / b division assignment
a %= b // a = a % b remainder assignment
a &&= b // a = a && b logical AND assignment
a ||= b // a = a || b logical OR assignment
```
