newcommand
The newcommand extension provides the \def, \newcommand,
\renewcommand, \let, \newenvironment, and
\renewenvironment macros for creating new macros and environments
in TeX. For example,
\(
\def\RR{{\bf R}}
\def\bold#1{{\bf #1}}
\)
defines a macro \RR that produces a bold “R”, while
\bold{math} typesets its argument using a bold font. See
Defining TeX macros for more information.
This extension is already loaded in all the components that
include the TeX input jax, other than input/tex-base. To load the
newcommand extension explicitly (when using input/tex-base for
example), add '[tex]/newcommand' to the load array of the
loader block of your MathJax configuration, and add
'newcommand' to the packages array of the tex block.
window.MathJax = {
loader: {load: ['[tex]/newcommand']},
tex: {packages: {'[+]': ['newcommand']}}
};
Alternatively, use \require{newcommand} in a TeX expression to load it
dynamically from within the math on the page, if the require
package is loaded.
Since the nnewcommand extension is included in the combined components that contain the TeX input jax, it may already be in the package list. In that case, if you want to disable it, you can remove it:
window.MathJax = {
tex: {packages: {'[-]': ['newcommand']}}
};
