How to remove the first and the last character of a string

String loginToken="[wdsd34svdf]";
System.out.println(loginToken.substring(1, loginToken.length()-1));
//Here you go

var yourString = "/installers/";
var result = yourString.substring(1, yourString.length-1);

console.log(result);




//Or you can use .slice as suggested by Ankit Gupta

var yourString = "/installers/services/";

var result = yourString.slice(1,-1);

console.log(result);
