megabytes and kilobytes

0. Reply content: If you use Node. js, can you use it if you don't need npm to pull dozens of hundreds of megabytes of data? The python installation package looks like a dozen mb. It was just yesterday that node was used. During the installation, it was only 5 MB in size and thought it was lightweight. When you started writing code, didn't you always download various packages from npm? In a project, there are more than 10 MB of npm packages, not a s

Sharing of the four digital kilobytes of characters formatting methods implemented by JS, js kilobytes The so-called number is represented by a comma (,) between each three digits starting from the single digit. For example, "10,000 ". In response to this requirement, I initially wrote a function like this:Copy codeThe Code is as follows:// Method 1Function toThousands (num ){Var result = [], counter = 0;Nu

There are no case-sensitive points.The meaning of B/s is: How many bytes of data are passed per second.The meaning of kb/s is how many

Format the value after rounding, with a kilobytes

Javascript converts numeric values to the amount format (separated by kilobytes and automatically added decimal points), and javascript decimal points In the project, if a number similar to '123' needs to be converted into the accounting format, '123' is automatically filled when the number of sub-places is separated by two digits after the decimal point is not enough, several implementation methods have been recorded Ps: if you do not consider the de

Please implement a js script, which requires that the number be converted into kilobytes, for example, 10000 is converted to 10,000Implement a js script to convert the number into a kilobytesFor example:10000 ----> 10,000 10000121213 ----> 10,000,121,213 I accidentally saw this question today and thought about four solutions to share with you: // Method 1 function parseNum (num) {var list = new String (num ). split (''). reverse (); for (var I = 0; I

In today's project, we need to display the number of clicks in the article on the page, which is tens of thousands of requests. Although it is not difficult, it has been a programmer for so long, it is no longer a simple implementation, and it is efficient and fast. Although the built-in function number_format () in PHP can achieve sub-bits, what I want is a ten-thousandth bit. In today's project, we need to display the number of clicks in the article on the page, which is tens of thousands of
