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.

How to work with dates and times in js?
Jul 01, 2025 am 01:27 AM
The following points should be noted when processing dates and time in JavaScript: 1. There are many ways to create Date objects. It is recommended to use ISO format strings to ensure compatibility; 2. Get and set time information can be obtained and set methods, and note that the month starts from 0; 3. Manually formatting dates requires strings, and third-party libraries can also be used; 4. It is recommended to use libraries that support time zones, such as Luxon. Mastering these key points can effectively avoid common mistakes.

What is event bubbling and capturing in the DOM?
Jul 02, 2025 am 01:19 AM
Event capture and bubble are two stages of event propagation in DOM. Capture is from the top layer to the target element, and bubble is from the target element to the top layer. 1. Event capture is implemented by setting the useCapture parameter of addEventListener to true; 2. Event bubble is the default behavior, useCapture is set to false or omitted; 3. Event propagation can be used to prevent event propagation; 4. Event bubbling supports event delegation to improve dynamic content processing efficiency; 5. Capture can be used to intercept events in advance, such as logging or error processing. Understanding these two phases helps to accurately control the timing and how JavaScript responds to user operations.
