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;

```

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