solve a differential equation for a variable in javascript

There are several libraries in JavaScript for solving differential equations such as mathjs, ode.js. Here is an example of how to solve differential equations using the mathjs library.

index.tsx
const math = require('mathjs')

// Define the differential equation
const differentialEquation = math.parse('y\'=x + y');

// Define the initial value
const initialValue = {
  x: 0,
  y: 1
};

// Define the variable to solve
const variableToSolve = 'y';

// Solve the differential equation
const solution = math.ode.solve(differentialEquation, initialValue, variableToSolve);

console.log(solution);

In this example, we define a differential equation y' = x + y, an initial value {x: 0, y: 1}, and a variable to solve y. We then use the math.ode.solve() function to solve the differential equation and store the result in solution. Finally, we log the solution to the console.

The output will be an array of x and y values.
