❓ FAQ
QWhat is the difference between var and code?
A
<var> specifically marks variable names — variables in math expressions or programs (like <var>x</var>) — rendered italic by default; <code> covers any code fragment. Variables use var, code uses code; each keeps its own semantics.QIs var suitable for math formulas?
AYes — the default italic rendering matches mathematical typesetting conventions. Simple inline formulas (such as
<var>x</var> = <var>y</var> + 1) are fine with var; complex formulas should use MathML, KaTeX, or another dedicated typesetting solution.QShould function names also use var in programming tutorials?
ANo. Variable names use
<var>, while function names, keywords, and class names conventionally use <code>. Rule of thumb: identifiers that get assigned a value use var; other code entities use code — and stay consistent throughout.🏷️ Related Tags
