Any simplest way to get cookie value in javascript

Question

I search Google but found entire functions to get cookie value. Isn\'t there one line statement to retrieve cookie value in javascript?

Answer 1

You can use the following one liner to convert your cookie to a map and then access whatever parameter you need.

let cookieMap = document.cookie.split(";").map((str)=>str.split("=")).reduce(function(map,curr){map[curr[0]]=curr[1];return map},{})
