JSForm

JSForm(expr)

returns the JavaScript form of the expr.

JSForm(expr, "Mathcell")

returns the JavaScript form of the expr with ‘Mathcell’ flavor output.

JSForm generates JavaScript output for the following JavaScript libraries:

• github.com/jsxgraph/jsxgraph
• github.com/paulmasson/math
• github.com/paulmasson/mathcell

This JavaScript flavour is also used in the [Manipulate](/calculator-usages/symja/functions/manipulate) function.

• developer.mozilla.org - Global Objects Math

Examples

Generate output for JavaScript floating-point arithmetic expressions:

>> JSForm(E^3-Cos(Pi^2/x))
(20.085536923187664)-Math.cos((9.869604401089358)/x)

Generate output for MathCell and Math JavaScript libraries:

>> JSForm(4*EllipticE(x)+KleinInvariantJ(t)^3, "Mathcell")
add(mul(4,ellipticE(x)),pow(kleinJ(t),3))

With JSForm you can display the generated JavaScript form of the Manipulate function

>> Manipulate(Plot(Sin(x)*Cos(1 + a*x), {x, 0, 2*Pi}), {a,0,10}) // JSForm
