I run your code in SpiderMonkey:
// SpiderMonkey javascript. By William James.
function normal(v) {
var div=Math.sqrt(v.map(function(x) x*x).reduce(function(a,b) a+b))
return v.map(function(x) x/div)
}
print normal [3,4];
i got:
/Users/xah/Documents/temp/xx.js:3: SyntaxError: missing { before
function body:
/Users/xah/Documents/temp/xx.js:3: var div=Math.sqrt(v.map(function(x)
x*x).reduce(function(a,b) a+b))
