How can JavaScript convert numbers into English words?

JavaScript Numbers to Words

In JavaScript, converting numbers into English words can be a complex task. However, by following a systematic approach, this conversion can be achieved with greater accuracy. One approach involves dividing the number into groups of three and converting each group separately.

Breaking Numbers into Groups

The first step is to separate the digits into groups of three from right to left. For example, the number 1234 would be divided into:

[1, 2, 3, 4]

This division is stored in an array called finlOutPut, which reads from right to left.

Converting Individual Groups

Next, each group of three digits is converted to a word using the triConvert function. This function handles the following cases:

• 1 to 99: This range is converted using two arrays, ones and tens.
• 100 to 999: This range is converted using the words "hundred," "ones," and "tens."

If all the digits in a group are zero, triConvert returns "dontAddBigSuffix" to indicate that no suffix should be added for larger groups.

Adding Thousands, Millions, etc.

As we convert groups from right to left, we also add suffixes like "thousand," "million," or "billion" to the appropriate groups. We use an array called bigNumArry to store these suffixes.

If a group equals "dontAddBigSuffix," we don't add any suffix and set the group to " " (nothing) in the finlOutPut array.

Final Conversion

The final step is to convert the array finlOutPut into a single, more readable string that represents the English words for the given number.

for(n = 0; n<finlOutPut.length; n++){
   output +=finlOutPut[n];
}

By combining these steps, the code accurately converts numbers into English words. However, it's important to note that there could be various optimization and error-handling improvements to make the code more robust and efficient.
