### JSONToDate
|
||||
|
||||
Converts a JSON object to a date.
|
||||
|
||||
Use `Date()`, to convert dates in JSON format to readable format (`dd/mm/yyyy`).
|
||||
|
||||
```js
|
||||
const JSONToDate = arr => {
|
||||
const dt = new Date(parseInt(arr.toString().substr(6)));
|
||||
return `${dt.getDate()}/${dt.getMonth() + 1}/${dt.getFullYear()}`;
|
||||
};
|
||||
```
|
||||
|
||||
<details>
|
||||
<summary>Examples</summary>
|
||||
|

```js
|

JSONToDate(/Date(1489525200000)/); // "14/3/2017"

|
||||
### speechSynthesis
|
||||
|
||||
Performs speech synthesis (experimental).
|
||||
|
||||
Use `SpeechSynthesisUtterance.voice` and `window.speechSynthesis.getVoices()` to convert a message to speech.
|
||||
Use `window.speechSynthesis.speak()` to play the message.
|
||||
|
||||
Learn more about the [SpeechSynthesisUtterance interface of the Web Speech API](https://developer.mozilla.org/en-US/docs/Web/API/SpeechSynthesisUtterance).
|
||||
|
||||
```js
|
||||
const speechSynthesis = message => {
|
||||
const msg = new SpeechSynthesisUtterance(message);
|
||||
msg.voice = window.speechSynthesis.getVoices()[0];
|
||||
window.speechSynthesis.speak(msg);
|
||||
};
|
||||
```
|
||||
|
||||
<details>
|
||||
<summary>Examples</summary>
|

### binarySearch
|
||||
|
||||
Use recursion. Similar to `Array.indexOf()` that finds the index of a value within an array.
|
||||
The difference being this operation only works with sorted arrays which offers a major performance boost due to it's logarithmic nature when compared to a linear search or `Array.indexOf()`.
|
||||
|
||||
Search a sorted array by repeatedly dividing the search interval in half.
|
||||
Begin with an interval covering the whole array.
|
||||
If the value of the search is less than the item in the middle of the interval, recurse into the lower half. Otherwise recurse into the upper half.
|
||||
Repeatedly recurse until the value is found which is the mid or you've recursed to a point that is greater than the length which means the value doesn't exist and return `-1`.
|
||||
|
||||
```js
|
||||
const binarySearch = (arr, val, start = 0, end = arr.length - 1) => {
|
||||
if (start > end) return -1;
|
||||
const mid = Math.floor((start + end) / 2);
|
||||
if (arr[mid] > val) return binarySearch(arr, val, start, mid - 1);
|
||||
if (arr[mid] < val) return binarySearch(arr, val, mid + 1, end);
|
||||
return mid;
|
||||
}
|
||||
```
|
||||
|
||||
<details>
|
||||
<summary>Examples</summary>
|
||||
|
||||
```js
|
||||
binarySearch([1, 4, 6, 7, 12, 13, 15, 18, 19, 20, 22, 24], 6); // 2
|
||||
binarySearch([1, 4, 6, 7, 12, 13, 15, 18, 19, 20, 22, 24], 21); // -1

### collatz
|
||||
|
||||
Applies the Collatz algorithm.
|
||||
|
||||
If `n` is even, return `n/2`. Otherwise, return `3n+1`.
|
||||
|
||||
```js
|
||||
const collatz = n => (n % 2 == 0 ? n / 2 : 3 * n + 1);
|
||||
```

### countVowels
|
||||
|
||||
Retuns `number` of vowels in provided string.
|
||||
|
||||
Use a regular expression to count the number of vowels `(A, E, I, O, U)` in a `string`.
|
||||
|
||||
```js
|
||||
const countVowels = str => (str.match(/[aeiou]/gi) || []).length;
|
||||
```
|
||||
|
||||
<details>
|
||||
<summary>Examples</summary>
|

|
||||
### factors
|
||||
|
||||
Returns the array of factors of the given `num`.
|
||||
If the second argument is set to `true` returns only the prime factors of `num`.
|
||||
If `num` is `1` or `0` returns an empty array.
|
||||
If `num` is less than `0` returns all the factors of `-int` together with their additive inverses.
|
||||
|
||||
Use `Array.from()`, `Array.map()` and `Array.filter()` to find all the factors of `num`.
|
||||
If given `num` is negative, use `Array.reduce()` to add the additive inverses to the array.
|
||||
Return all results if `primes` is `false`, else determine and return only the prime factors using `isPrime` and `Array.filter()`.
|
||||
Omit the second argument, `primes`, to return prime and non-prime factors by default.
|
||||
|
||||
**Note**:- _Negative numbers are not considered prime._
|
||||
|
||||
```js
|
||||
const factors = (num, primes = false) => {
|
||||
const isPrime = num => {
|
||||
const boundary = Math.floor(Math.sqrt(num));
|
||||
for (var i = 2; i <= boundary; i++) if (num % i === 0) return false;
|
||||
return num >= 2;
|

};
|

const isNeg = num < 0;
|

num = isNeg ? -num : num;

```js
|

Generates an array, containing the Fibonacci sequence, up until the nth term.
|
||||
|

Create an empty array of the specific length, initializing the first two values (`0` and `1`).
|
||||
Use `Array.reduce()` to add values into the array, using the sum of the last two values, except for the first two.
|
||||
Uses a mathematical formula to calculate the length of the array required.
|
||||
|
||||
```js
|
||||
const fibonacciUntilNum = num => {
|

let n = Math.ceil(Math.log(num * Math.sqrt(5) + 1 / 2) / Math.log((Math.sqrt(5) + 1) / 2));

||||
If the parameter `desc` is truthy, return array sorts in descending order.

||||
|
||||
```js

### solveRPN
|
||||
|
||||
Solves the given mathematical expression in [reverse polish notation](https://en.wikipedia.org/wiki/Reverse_Polish_notation).
|
||||
Throws appropriate errors if there are unrecognized symbols or the expression is wrong. The valid operators are :- `+`,`-`,`*`,`/`,`^`,`**` (`^`&`**` are the exponential symbols and are same). This snippet does not supports any unary operators.
|
||||
|
||||
Use a dictionary, `OPERATORS` to specify each operator's matching mathematical operation.
|
||||
Use `String.replace()` with a regular expression to replace `^` with `**`, `String.split()` to tokenize the string and `Array.filter()` to remove empty tokens.
|
||||
Use `Array.forEach()` to parse each `symbol`, evaluate it as a numeric value or operator and solve the mathematical expression.
|
||||
Numeric values are converted to floating point numbers and pushed to a `stack`, while operators are evaluated using the `OPERATORS` dictionary and pop elements from the `stack` to apply operations.
|
||||
|
||||
```js
|
||||
const solveRPN = rpn => {
|
||||
const OPERATORS = {
|
||||
'*': (a, b) => a * b,
|
||||
'+': (a, b) => a + b,
|
||||
'-': (a, b) => a - b,
|
||||
'/': (a, b) => a / b,
|
||||
'**': (a, b) => a ** b
|
||||
};
|
||||
const [stack, solve] = [
|
||||
[],
|
||||
rpn
|
||||
.replace(/\^/g, '**')
|
||||
.split(/\s+/g)
|
||||
.filter(el => !/\s+/.test(el) && el !== '')
|
||||
];
|
||||
solve.forEach(symbol => {
|
||||
if (!isNaN(parseFloat(symbol)) && isFinite(symbol)) {
|
||||
stack.push(symbol);
|
||||
} else if (Object.keys(OPERATORS).includes(symbol)) {
|
||||
const [a, b] = [stack.pop(), stack.pop()];
|
||||
stack.push(OPERATORS[symbol](parseFloat(b), parseFloat(a)));
|
||||
} else {
|
||||
throw `${symbol} is not a recognized symbol`;
|
||||
}
|
||||
});
|
||||
if (stack.length === 1) return stack.pop();
|
||||
else throw `${rpn} is not a proper RPN. Please check it and try again`;
|
||||
};

||||
```

### howManyTimes
|
||||
|
||||
Returns the number of times `num` can be divided by `divisor` (integer or fractional) without getting a fractional answer.
|
||||
Works for both negative and positive integers.
|
||||
|
||||
If `divisor` is `-1` or `1` return `Infinity`.
|
||||
If `divisor` is `-0` or `0` return `0`.
|
||||
Otherwise, keep dividing `num` with `divisor` and incrementing `i`, while the result is an integer.
|
||||
Return the number of times the loop was executed, `i`.
|
||||
|
||||
```js
|
||||
const howManyTimes = (num, divisor) => {
|
||||
if (divisor === 1 || divisor === -1) return Infinity;
|
||||
if (divisor === 0) return 0;
|
||||
let i = 0;
|
||||
while (Number.isInteger(num / divisor)) {
|
||||
i++;
|
||||
num = num / divisor;
|
||||
}
|
||||
return i;
|
||||
};
|
||||
```
|
||||
|
||||
<details>
|
||||
<summary>Examples</summary>
|
||||
|
||||
```js
|
||||
howManyTimes(100, 2); // 2
|
||||
howManyTimes(100, 2.5); // 2
|
||||
howManyTimes(100, 0); // 0
|
||||
howManyTimes(100, -1); // Infinity
