javascript adding strings together

Question

var body = "jsonString=123";
var mybody = body.replace("jsonString=","");
console.log("mybody:"+mybody);
console.log("myhead:"+body.replace("jsonString=",""));

This this should give two equal outputs to console.log file but it doesnt!

Output:
mybody:
myhead:123

Can someone explain why variable mybody is blank? Shouldnt it be 123?

EDIT I am such a fool, there were some unrelated problems with my execution environment that led to this. It has nothing to do with javascript. Thanks for the help SO

Works for me, the only thing I can think of is it's trying to add a string to the number 123, so you can convert mybody to a string like mybody.toString() — JKirchartz

Where are you running this? I just copy and pasted your code into a node REPL console and I saw what you EXPECTED to see (i.e. mybody:123) — Rich Turner
