• it contains tests
• KaTeX with React is much better than MathJax
• supports macros! (example of usage in demo - replacing \cdot with asterisk *)
• smaller (1.8 kB minified, 920 B gzip)
• much more readable internal code (no weird quirks with mathjax lib)
• LaTeX is better than AsciiMath (KaTeX supports only LaTeX math)
• react and katex are in pkg.devDependencies (user now has power to update dependencies)
• ...

Here is better maintained repo: https://github.com/wko27/react-mathjax

React component to display math formulas written in AsciiMath or TeX.

Based on the react-mathjax from SamyPesse. The main difference is in updated deps, syntax and extended options (delay of rendering and support for AsciiMath).

npm install @matejmazur/react-mathjax

const MathJax = require('@matejmazur/react-mathjax')
const ascii = 'U = 1/(R_(si) + sum_(i=1)^n(s_n/lambda_n) + R_(se))'
const tex = `f(x) = \\int_{-\\infty}^\\infty\\hat f(\\xi)\\,e^{2 \\pi i \\xi x}\\,d\\xi`

module.exports = () => {
    return (
        <div>
            <MathJax.Context>
                <div>
                    This is an inline math formula: <MathJax.Node inline>{'a = b'}</MathJax.Node>
                    And a block one:

                    <MathJax.Node>{ascii}</MathJax.Node>
                </div>
            </MathJax.Context>

            <MathJax.Context input='tex'>
                <div>
                    This is an inline math formula: <MathJax.Node inline>{'a = b'}</MathJax.Node>
                    And a block one:

                    <MathJax.Node>{tex}</MathJax.Node>
                </div>
            </MathJax.Context>
        </div>
    );
}
