Parse an HTTP Cookie header string and return an object of all cookie name-value pairs
Example:
const parseCookie = str => str .split(';') .map(v => v.split('=')) .reduce((acc, v) => { acc[decodeURIComponent(v[0].trim())] = decodeURIComponent(v[1].trim()); return acc; }, {}); console.log(parseCookie('foo=bar; equation=E%3Dmc%5E2')); // { foo: 'bar', equation: 'E=mc^2' }
Output:
[object Object] { equation: "E=mc^2", foo: "bar" }
