Text & String

What do you do to format 1000 to 1,000 using Javascript? If you are a programmer, you may write a custom function to find length of the number and insert commas at required places. Numeral.js makes this task easy for you. It is a pure Javascript library for formatting and manipulating numbers. It does not have any dependencies and therefore it is very fast and right to the point.

Highlight.js highlights syntax in code examples on blogs, forums and, in fact, on any web page. It's very easy to use because it works automatically: finds blocks of code, detects a language, highlights it.

Math.js is an extensive math library for JavaScript and Node.js. It features a flexible expression parser and offers an integrated solution to work with numbers, big numbers, complex numbers, units, and matrices. Powerful and easy to use.
