Tests:

Atob decode
var features = window.getCookie('features'); let decodedData = false; function jwtDecode(t) { let token = {}; token.raw = t; token.header = window.atob(t.split('.')[0]); token.payload = window.atob(t.split('.')[1]); return token; } try { decodedData = features === undefined ? false : jwtDecode('features'); // decode the string } catch (e) {} let result = decodedData ? decodedData.payload.includes('free:true') : false;
Check for value
var features = window.getCookie('features'); features.includes('eyJ');
No header decode
var features = window.getCookie('features'); let decodedData = false; function jwtDecode(t) { let token = {}; token.raw = t; token.payload = window.atob(t.split('.')[1]); return token; } try { decodedData = features === undefined ? false : jwtDecode('features'); // decode the string } catch (e) {} let result = decodedData ? decodedData.payload.includes('free:true') : false;
longer string decode
var features = window.getCookie('monsterfeatures'); let decodedData = false; function jwtDecode(t) { let token = {}; token.raw = t; token.header = window.atob(t.split('.')[0]); token.payload = window.atob(t.split('.')[1]); return token; } try { decodedData = features === undefined ? false : jwtDecode('features'); // decode the string } catch (e) {} let result = decodedData ? decodedData.payload.includes('free:true') : false;
