# --description--
|
||
|
|
|
||
|
|
In JavaScript, you can store a value in a variable with the <dfn>assignment</dfn> operator (`=`).
|
||
|
|
|
||
|
|
`myVariable = 5;`
|
||
|
|
|
||
|
|
This assigns the `Number` value `5` to `myVariable`.
|
||
|
|
|
||
|
|
If there are any calculations to the right of the `=` operator, those are performed before the value is assigned to the variable on the left of the operator.
|
||
|
|
|
||
|
|
```js
|
||
|
|
var myVar;
|
||
|
|
myVar = 5;
|
||
|
|
```
|
||
|
|
|
||
|
|
First, this code creates a variable named `myVar`. Then, the code assigns `5` to `myVar`. Now, if `myVar` appears again in the code, the program will treat it as if it is `5`.
|
||
|
|
|
||
|
|
# --instructions--
|
||
|
|
|
||
|
|
Assign the value `7` to variable `a`.
|
||
|
|
|
||
|
|
# --hints--
|
||
|
|
|

|
|
You should not change code above the specified comment.
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(/var a;/.test(code));
|
||
|
|
```
|
||
|
|
|
||
|
|
`a` should have a value of 7.
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(typeof a === 'number' && a === 7);
|
||
|
|
```
|
