How to create a curve object.

[jawar-cn]

I'm trying to use snarkjs in javascript .

When I new a power of tau

const zkSnark = require("snarkjs");
await zkSnark.powersOfTau.newAccumulator(curve, 14, "pot14_0000.ptau")

I really don't know how and where to get a curve object.

And I find a mothod in snarkjs named getCurveFromName which is not defined by "exports" in package.json

Curves are created when they are needed and then they are available on the global, such as globalThis.curve_bn128

I use
console.log(globalThis)
and console shows

<ref *1> Object [global] {
  global: [Circular *1],
  queueMicrotask: [Function: queueMicrotask],
  clearImmediate: [Function: clearImmediate],
  setImmediate: [Function: setImmediate] {
    [Symbol(nodejs.util.promisify.custom)]: [Getter]
  },
  structuredClone: [Getter/Setter],
  clearInterval: [Function: clearInterval],
  clearTimeout: [Function: clearTimeout],
  setInterval: [Function: setInterval],
  setTimeout: [Function: setTimeout] {
    [Symbol(nodejs.util.promisify.custom)]: [Getter]
  },
  atob: [Getter/Setter],
  btoa: [Getter/Setter],
  performance: [Getter/Setter],
  fetch: [AsyncFunction: fetch],
  crypto: [Getter],
  curve_bn128: null,
  curve_bls12381: null
}

the curve_bn128 object is null.
