[Anton3210]

Running a dict containing a Spreadoperator gives an error:

babel/parser.parse() on this : const a = {'a':'b','b':'b','c':'c'}; const b = {'z':'z'}; const y = {...a,...b};

gives Following error:

I am getting the same error. Is this library still being maintained at all?

I´m using acorn now

import * as acorn_walk from 'acorn-walk'; import { ancestor } from 'acorn-walk'; function findNodeByValue(ast, value) { let path = []; let callback = function(){} let functionBase = {...acorn_walk.base}; functionBase.Literal = function(node,_state,ancestor){ count++; if (node.value==value) { path.push({"node":node,"ancestor":ancestor}) } } acorn_walk.fullAncestor(ast,function(a,b,c){},functionBase );//node, callback, baseVisitor, state, override

return path;

} ast = acorn.parse(strings,{ // parse in strict mode and allow module declarations sourceType: "script", ecmaVersion : 12,

plugins: [ // enable jsx and flow syntax "jsx", "flow", ], })

This package worked perfectly for me. Thanks for pointing it out.
