### isSimilar

Determines if the `pattern` matches with `str`.

Use `String.toLowerCase()` to convert both strings to lowercase, then loop through `str` and determine if it contains all characters of `pattern` and in the correct order.

```js
const isSimilar = (pattern, str) =>
  [...str].reduce(
    (matchIndex, char) =>
      char.toLowerCase() === (pattern[matchIndex] || '').toLowerCase()
        ? matchIndex + 1
        : matchIndex,
    0
  ) === pattern.length
    ? true
    : false;
```

```js
isSimilar('rt','Rohit'); // true
isSimilar('tr','Rohit'); // false
```
