How to write character validation in a string?

Question

JavaScript

There is such an object, where the keys are the strings that need to be validated
. After applying the written method, valid / invalid should be displayed.
Open brackets should be matched with closed ones and quotes are parsed in pairs

const inputs = {
  'erh43t26s5jemaslvjhgjfd': true, //valid
  'erh43"#tje#(maslg)fvjh"gjfd': true, //valid
  'erh43"tje(maslg"fvjh)gjfd': false, //invalid
  'erh43"tje(maslg"fvj"h)gj"fd': true, //valid !!!!!
  'erh4{3tjem[aslvv]jhg}jfd': true, //valid
  'e"r"h"{4(3dsad)tj324ema}"slv"jhg"jfd': true, //valid
  'e"r[h"{4(3dsad)tj324ema}"slv]jhg"jfd': true, //valid !!!!!
  'e"r["h"{4(3dsad)tj324ema}slv]jhg"jfd': true, //valid !!!!!
  'erh4\'3tj(er#y{ut#maslv)jh}\'gjfd': false, //invalid
  'erh4\'3tj(ery{utmas}lv)jh\'gjfd': true, //valid
  'erh4\'3\'tj(ery{utmas}lv)jh\'gjfd': false, //invalid !!!!!
  'erh4\'3\'tj(ery{utmas}lv)jh\'gjfd': false, //invalid !!!!!
  'erh4\'3\'"t"j(ery{utmas}lv)\'jh\'gjfd': true, //valid 
  'erh4\'3\'"tj(ery{utmas}lv)j"h\'gj\'fd': true, //valid
  'erh43#tjecmasy565lv#jhgjfd': true, //valid
}

First, make a list of paired characters - brackets and quotes.
Next, character by character, iterate over the string
. If there is an opening character, push it onto the stack.
If you meet a closing one, check if its pair is at the top of the stack. If there is - remove the opening one from the stack, if not - an error.
At the end of the line, check if the stack is empty. If not empty, there are unclosed brackets or quotes left.
