Here you go   x000D   x000D  var yourString     installers    x000D  var result   yourString substring 1  yourString length-1   x000D   x000D  console log result   x000D   x000D   x000D    Or you can use  slice as suggested by Ankit Gupta   x000D   x000D  var yourString     installers services    x000D   x000D  var result   yourString slice 1 -1   x000D   x000D  console log result   x000D   x000D   x000D    Documentation for the slice and substring

You can do something like that       installers services   replace       g     replace       g       This regex is a common way to have the same behaviour of the trim function used in many languages   A possible implementation of trim function is     function trim string  char       if  char  char          space by default     char   char replace                    g      1      escape char parameter if needed for regex syntax      var regex 1   new RegExp       char         g        var regex 2   new RegExp char          g        return string replace regex 1      replace regex 2           Which will delete all   at the beginning and the end of the string  It handles cases like    installers services     You can also simply do       installers   substring 1  string length-1

You could regex it    string  replace                    installers services   replace                     - gt  installers services   The regex explained  - Optional first slash       escaped -        the   means beginning of string  - The pipe       can be read as or - Than the option slash at the end -       escaped -         the   means end of string   Combined it would be        without escaping  Optional first slash OR optional last slash
