## UDE **Node Algorithms**

:computer:

A list of some algorithms solved using nodejs

### Run the tests

1. At the terminal, run `jest reverse/test.js --watch`

### Debug statements

1. Add a `debugger` statement in your function

    ```javascript

    const reverse(str) {

        debugger; // just write this in the code

        return str.split('').reverse().join('');

    }

    ```

2. Call the function manually in current file

    ```js

    reverse('asdf');

    ```

3. At the terminal, run `node inspect index.js`

4. To continue execution of the file, press `c` then `enter`.

    ```sh

    debug> cont -> continue until the debugger word

    ```

5. To launch a `repl` session, type `repl` then `enter`. 

    ```sh

    > repl -> enter the debug repl (ctrl + c to exit)

    > str -> to see str value

    ```

### Notes

 - `common string questions`

    - what is the most common character in a string?

    - does string A have the same characters as string B (Is it an anagram)?

    - does the given string have any repeated characters in it?

- convert the `string` in a `object` representation

    - `hello there!` -> 

        ```json

            {

                "H": 1,

                "e": 3,

                "l": 2,

                "o": 1,

                " ": 1,

                "T": 1,

                "h": 1,

                "r": 1,

                "!": 1

            }

        ```

    - transform in an object

    ```js

        const string = 'Hello There!';

        const chars = {};

        for(let char of string){

            chars[char] = chars[char] + 1 || 1;

        }

    ```
