Question on how to construct NodePaths

[not-jan]

I'm trying to simplify a piece of code. The code looks like this:

if (true) {
  console.log("true");
else {
  console.log("false");
}

The easiest way of implementing this would be to use the evaluateTruthy function from the utilities but that will only take a path. Is there any way of reusing that code for my purposes?

Sadly, it can't use anything other than nodepaths

Here is an MVP example to do this (if you have some confusions)

const { traverse, utils: u } = require('estree-toolkit')
const { parseModule } = require('meriyah')
const { generate } = require('astring')

const ast = parseModule(`
if (true) {
  console.log("true");
} else {
  console.log("false");
}
`)

traverse(ast, {
  IfStatement(path) {
    const res = u.evaluateTruthy(path.get('test'))
    if (res != null) {
      if (res) {
        path.replaceWith(structuredClone(path.get('consequent').node))
      } else {
        path.replaceWith(structuredClone(path.get('alternate').node))
      }
    }
  }
})

console.log('---------------')
console.log(generate(ast))

Thank you! :)

I was using consequent instead of alternate in else. I updated the code to fix that.
