# --description--
|
|
|
|
The `split` method splits a string into an array of strings. It takes an argument for the delimiter, which can be a character to use to break up the string or a regular expression. For example, if the delimiter is a space, you get an array of words, and if the delimiter is an empty string, you get an array of each character in the string.
|
|
|
|
Here are two examples that split one string by spaces, then another by digits using a regular expression:
|
|
|
|
```js
|
|
var str = "Hello World";
|
|
var bySpace = str.split(" ");
|
|
// Sets bySpace to ["Hello", "World"]
|
|
|
|
var otherString = "How9are7you2today";
|
|
var byDigits = otherString.split(/\d/);
|
|
// Sets byDigits to ["How", "are", "you", "today"]
|
|
```
|
|
|
|
Since strings are immutable, the `split` method makes it easier to work with them.
|
|
|
|
# --instructions--
|
|
|
|
Use the `split` method inside the `splitify` function to split `str` into an array of words. The function should return the array. Note that the words are not always separated by spaces, and the array should not contain punctuation.
|
|
|
|
# --hints--
|
|
|
|
Your code should use the `split` method.
|
|
|
|
```js
|
|
assert(code.match(/\.split/g));
|
|
```
|
|
|
|
`splitify("Hello World,I-am code")` should return `["Hello", "World", "I", "am", "code"]`.
|
|
|
|
```js
|
|
assert(
|
|
JSON.stringify(splitify('Hello World,I-am code')) ===
|
|
JSON.stringify(['Hello', 'World', 'I', 'am', 'code'])
|
|
);
|
|
```
|
|
|
|
`splitify("Earth-is-our home")` should return `["Earth", "is", "our", "home"]`.
|
|
|
|
```js
|
|
assert(
|
|
JSON.stringify(splitify('Earth-is-our home')) ===
|
|
JSON.stringify(['Earth', 'is', 'our', 'home'])
|
|
);
|
|
```
|
|
|
|
`splitify("This.is.a-sentence")` should return `["This", "is", "a", "sentence"]`.
|
|
|
|
```js
|
|
assert(
|
|
JSON.stringify(splitify('This.is.a-sentence')) ===
|
|
JSON.stringify(['This', 'is', 'a', 'sentence'])
|
|
);
|
|
```
