The textcomp extension implements the old textcomp style package from LaTeX. The macros of the package are now part of LaTeX’s base package. The textcomp extension provides a number of text macros that can be used in math mode as well. See the CTAN page for more information and documentation of textcomp.

This package is not autoloaded, so you must request it explicitly if you want to use it. To load the textcomp extension, add '[tex]/textcomp' to the load array of the loader block of your MathJax configuration, and add 'textcomp' to the packages array of the tex block. The macros provided in textcomp can be used equally in math and text mode. In order to make them available in text mode they have to be explicitly added to the packages of the textmacros extension.

window.MathJax = {
  loader: {load: ['[tex]/textmacros', '[tex]/textcomp']},
  tex: {packages: {'[+]': ['textmacros']}}
  textmacros: {packages: {'[+]': ['textcomp']}}

Alternatively, use \require{textcomp} in a TeX expression to load it dynamically from within the math on the page, if the require extension is loaded.
