// target file
function execute() { 
  var a = 'a'
}

// jscodeshift
export default(file, api) => {
  const j = api.jscodeshift
  const root = j(file.source)

  var node = root.find(j.VariableDeclaration)
  // i want to see what node looks like in javascript.

  return root.toSource()
}

Presumable there is a non empty collection of what you search for:

var node = root.find(j.VariableDeclaration).at(0).get();
// in js node looks like
return j(node).toSource();
