//This method adds two or more strings and returns a new single string.
let str1 = new String( "This is string one" );
let str2 = new String( "This is string two" );
let str3 = str1.concat(str2.toString());
console.log("str1 + str2 : "+str3)

Example 2: javascript push and concat
//push() adds element in the end of array
// concat() also the same, but if the element is array, that element will probably separate elements of itself in the end of the array
