var testString = "<this is the first string>and this is the second string";
Tests:

  • substring

     
    var firstString = testString.substring(1,24);
    var secondString = testString.substring(26);

  • split

     
    var splitArray = testString.split('<')[1].split('>');
    var firstString = splitArray[0];
    var secondString = splitArray[1];

  • slice

     
    var firstString = testString.slice(1,24);
    var secondString = testString.slice(26);
