String Operators



The most useful operator for strings is concatenation, represented by the + sign. 
Concatenation can be used to build strings by joining together multiple strings, or by joining strings with other types: 
var mystring1 = "I am learning ";
var mystring2 = "JavaScript with SoloLearn.";
document.write(mystring1 + mystring2);Try It Yourself

The above example declares and initializes two string variables, and then concatenates them.
Numbers in quotes are treated as strings: "42" is not the number 42, it is a stringthat includes two characters, 4 and 2.
What is the output of the following code:
var x = "50";
var y = "100";
document.write(x+y);
50100
5000
Null
150
