I have a problem, because everytime i need to write indexof, i need to use + for example:
String lsdfrom2 = '[' + '"' + "LSD" + ',' + '[' + ']' + ',' + '{' + '"' + "token" + '"' + ":" + '"';
How to write it in another way? thats soo anoying to write it like in example I mean, how to read text below without write every char singly
["LSD",[],{"token":"
