Write a JS function that finds, how many times a given word, is used in a given sentence. Note that letter case does not matter – it is case-insensitive.

The input comes as 2 string arguments:

• The first one will be the sentence
• The second one – the word.

Examples:

Input:
The waterfall was so high, that the child couldn’t see its peak.
the

Output:
2

Input:
How do you plan on achieving that? How? How can you even think of that?
how

Output:
3

Input:
There was one. Therefore I bought it. I wouldn’t buy it otherwise.
there

Output:
1

The output is a single number indicating the amount of times the sentence contains the word.

You are tasked to count the number of words in a text using a Map, any combination of letters, digits and _ (underscore) should be counted as a word. The words should be stored in a Map - the key being the word and the value being the amount of times the word is contained in the text. The matching should be case insensitive. Print the words in a sorted order.

The input comes as an array of strings containing one entry - the text whose words should be counted. The text may consist of more than one sentence.

Examples:

Input:
Far too slow, you're far too slow.

Output:
'far' -> 2 times
're' -> 1 times
'slow' -> 2 times
'too' -> 2 times
'you' -> 1 times

Input:
JS devs use Node.js for server-side JS. JS devs use JS. -- JS for devs --

Output:
'devs' -> 3 times
'for' -> 2 times
'js' -> 6 times
'node' -> 1 times
'server' -> 1 times
'side' -> 1 times
'use' -> 2 times

The output should be printed on the console - print each word in the map in the format "'<word>' -> <count> times", each on a new line.

Sample HTML:

<input type="text" id="num1" /> +
<input type="text" id="num2" /> =
<input type="text" id="sum" readonly="readonly" />
<input type="button" value="Calc" onclick="calc()" />
<script>
    function calc() { 
       // TODO: sum = num1 + num2
    }
</script>

Examples:

<ul id="items">
  <li>first item</li>
  <li>second item</li>
  <li>third item</li>
</ul>
<textarea id="result"></textarea>
<br>
<button onclick="extractText()">Extract Text</button>
<script>
  function extractText() {
    // TODO
  }
</script>

Examples:

<h1>List of Items</h1>
<ul id="items"><li>First</li><li>Second</li></ul>
<input type="text" id="newItemText" />
<input type="button" value="Add" onclick="addItem()">
<script>
  function addItem() {
    // TODO: add new item to the list
  }
</script>

Examples:

Write a JavaScript function that repeats a given string, N times.

The input comes as 2 arguments:

• The first argument is a string that will represent the one you need to repeat.
• The second one is a number will represent the times you need to repeat it.

Examples:

Input:
repeat
5

Output:
repeatrepeatrepeatrepeatrepeat

Input:
magic is real
3

Output:
magic is realmagic is realmagic is real

The output is a big string, containing the given one, repeated N times.

Write a JS function that splits a passed in JS code into separate parts.

The passed in code will always have one or more spaces between operators and operands. Normal brackets (‘(‘,’)’), commas (,), semicolons (;) and the member access operator (‘.’(dot), as in “console.log”) should also be used for splitting.
String literals will always be initialized with double quotes (") and will contain only letters. Make sure there are no empty entries in the output.

The input comes as a single string argument - the JS code that has to be split.

Examples:

Input:
'let sum = 4 * 4,b = "wow";'

Output:
let
sum
=
4
*
4
let
b
=
"wow"

Input:
'let sum = 1 + 2;if(sum > 2){\tconsole.log(sum);}'

Output:
let
sum
=
1
+
2
if
sum
>
2
{
console
log
sum
}

The output should be printed on the console, with each elements obtained from the split is printed on a new line.

You are tasked to write a javascript function that receives an array of purchases and their prices and prints all your purchases and their total sum.

The input comes as an array of string elements – the elements on even indexes (0, 2, 4…) are the product names, while the elements on odd indexes (1, 3, 5…) are the corresponding prices.

Examples:

Input:


Output:
You purchased Beer Zagorka, Tripe soup, Lasagna for a total sum of 16.14

Input:


Output:
You purchased Cola, Pancakes for a total sum of 4.23

The output should be printed on the console - a single sentence containing all products and their total sum in the format “You purchased {all products separated by comma + space} for a total sum of {total sum of products}”.
