# --description--
|
||
|
||
`/=` 操作符是讓變量與另一個數相除並賦值。
|
||
|
||
```js
|
||
myVar = myVar / 5;
|
||
```
|
||
|
||
將 `myVar` 除以 `5`。 等價於：
|
||
|
||
```js
|
||
myVar /= 5;
|
||
```
|
||
|
||
# --instructions--
|
||
|
||
使用 `/=` 操作符對 `a`，`b` 和 `c` 實現相除賦值操作。
|
||
|
||
# --hints--
|
||
|
||
`a` 應該等於 `4`。
|
||
|
||
```js
|
||
assert(a === 4);
|
||
```
|
||
|
||
`b` 應該等於 `27`。
|
||
|
||
```js
|
||
assert(b === 27);
|
||
```
|
||
|
||
`c` 應該等於`3`。
|
||
|
||
```js
|
||
assert(c === 3);
|
||
```
|
||
|
||
應該對每個變量使用 `/=` 操作符。
|
||
|
||
```js
|
||
assert(code.match(/\/=/g).length === 3);
|
||
```
|
||
|
||
不要修改註釋上面的代碼。
|
||
|
||
```js
|
||
assert(
|
||
/let a = 48;/.test(code) &&
|
||
/let b = 108;/.test(code) &&
|
||
/let c = 33;/.test(code)
|
||
);
|
||
```

let a = 48;

let b = 108;
|

let c = 33;
|
||
|
||
// Only change code below this line
|
||
a = a / 12;
|
||
b = b / 4;
|
||
c = c / 11;
|

```

```js

let a = 48;
|
||
let b = 108;
|
||
let c = 33;
|
||
|
||
a /= 12;
|
||
b /= 4;
|
||
c /= 11;

```
