Sort The Dictionary Array Keys Using JavaScript And Output

Sort The Below Dictionaryarray Key Using Javascript And Output The In

Sort the below dictionary/array key using Javascript and output the information in key:value format on a Polymer interface. The entire numeric key should be sorted in an ascending order and all the alpha keys should be sorted in ASCII, ascending order. Dictionary = {„34”: „thirty-four”, „90”: „ninety”, „91”: „ninety-one”„21”: „twenty-one”, „61”: „sixty-one”, „9”: „nine”, „2”: „two”, „6”: „six”, „3”: „three”, „8”: „eight”, „80”: „eighty”, „81”: „eighty-one”, „Ninety-Nine”: „99”, „nine-hundred”: „900”}

Paper For Above instruction

To effectively sort and display a complex JavaScript dictionary containing both numeric and alphabetic keys, we must first parse the object accordingly. The primary goal is to order numeric keys in ascending numeric order and alphabetic keys in ASCII order, then output the key-value pairs in a readable format suitable for a Polymer interface.

Given the dictionary:

{

"34": "thirty-four", 


"90": "ninety", 


"91": "ninety-one",


"21": "twenty-one", 


"61": "sixty-one", 


"9": "nine", 


"2": "two", 


"6": "six", 


"3": "three", 


"8": "eight", 


"80": "eighty", 


"81": "eighty-one", 


"Ninety-Nine": "99", 


"nine-hundred": "900"


}

First, the object should be separated into numeric and alphabetic keys. Numeric keys can be distinguished by checking if they can be coerced to a number without resulting in NaN. After separation, numeric keys are converted to integers, sorted in ascending order, and then the alphabetic keys are sorted based on ASCII value, which can be achieved with standard string comparison.

For the numeric keys, the sorting process involves converting string keys to numbers, sorting numerically, and then converting back to strings if needed. For example, the numeric keys include "2", "3", "6", "8", "9", "21", "34", "61", "80", "81", "90", and "91". The alphabetic keys are "Ninety-Nine" and "nine-hundred". In ASCII sorting, uppercase letters come before lowercase letters, meaning "Ninety-Nine" would appear before "nine-hundred" because 'N' (ASCII 78) is less than 'n' (ASCII 110).

Once sorted, the pairs are prepared for output in the key:value format. We leverage JavaScript’s Object.entries() combined with sorting algorithms. The sorted keys are then iterated over to produce output suitable for a Polymer interface, typically as list items or plain text, depending on the structuring requirements.

Implementing this process ensures that all numeric keys are ordered from smallest to largest and all alphabetic keys follow in ASCII order, thereby creating a clean, ordered presentation of the dictionary data in the web interface.
