The more correct solution is to do what Math. This avoids making an unfulfilled promise of universal uniqueness, while allowing for much simpler code. Also, in javascript where Math. That makes for a staggering 5. If every person on the planet filled up a terabyte hard drive with nothing but random UUIDs, there would only be a one in 7 trillion chance that two of the UUIDs would be the same.

The practice is probably a little different. The uniqueness depends on how random the numbers generated by Math.

Generating truly random numbers is a notoriously tricky problemsolved in different imperfect ways across browser platforms and OSes.

Regardless, this is a weakness that all javascript UUID generators will be subject to, unless they rely on an externally-provided unique value. Several people have expressed concern over how random the Math. Seeding is done from a variety of sources of almost pure random numbers — mouse movement, built-in hardware support [email protected]: This is the answer.

A JavaScript function is defined with the function keyword, followed by a name, followed by parentheses (). Function names can contain letters, digits, underscores, and dollar signs (same rules as variables).

I am wondering if JavaScript supports writing a function within another function, or nested functions (I read it in a blog). Is this really possible?. In fact, I have used these but am unsure of this.

init() creates a local variable called name and a function called displayName().The displayName() function is an inner function that is defined inside init() and is only available within the body of the init() function.

The displayName() function has no local variables of its own. However, because inner functions have access to the variables of outer functions, displayName() can access the.
