# --description--
|
|
|
|
Previously you used the following code to declare a variable:
|
|
|
|
```js
|
|
var myName;
|
|
```
|
|
|
|
But you can also declare a string variable like this:
|
|
|
|
```js
|
|
var myName = "your name";
|
|
```
|
|
|
|
`"your name"` is called a <dfn>string</dfn> <dfn>literal</dfn>. A string literal, or string, is a series of zero or more characters enclosed in single or double quotes.
|
|
|
|
# --instructions--
|
|
|
|
Create two new string variables: `myFirstName` and `myLastName` and assign them the values of your first and last name, respectively.
|
|
|
|
# --hints--
|
|
|
|
`myFirstName` should be a string with at least one character in it.
|
|
|
|
```js
|
|
assert(
|
|
(function () {
|
|
if (
|
|
typeof myFirstName !== 'undefined' &&
|
|
typeof myFirstName === 'string' &&
|
|
myFirstName.length > 0
|
|
) {
|
|
return true;
|
|
} else {
|
|
return false;
|
|
}
|
|
})()
|
|
);
|
|
```
|
|
|
|
`myLastName` should be a string with at least one character in it.
|
|
|
|
```js
|
|
assert(
|
|
(function () {
|
|
if (
|
|
typeof myLastName !== 'undefined' &&
|
|
typeof myLastName === 'string' &&
|
|
myLastName.length > 0
|
|
) {
|
|
return true;
|
|
} else {
|
|
return false;
|
|
}
|
|
})()
|
|
);
|
|
```
