Any way to assign a variable (not an object property) another variable's value by reference in JavaScript? -

-

so, here's need:

var = 5; var b = a; = 6; alert(b) // want alert 6 not 5

i've seen questions how variable assignment work in javascript?, answers https://stackoverflow.com/a/509614/1117796 , posts http://hpyblg.wordpress.com/2010/05/30/simulating-pointers-in-javascript/. not want use objects/hashes/dictionaries or whatever else want call them. want done plain variables containing plain primitive values. php assignment reference: $b = &$a;. @ possible? comes near it?

no isin't possible pass simple values reference in javascript.

however javascript flexible language , possibly implement similar using object.defineproperty providing setters , getters work same variable. work global variables however, there's no way mimic behaviour. instance, since can't reference execution scope of functions, not able emulate concept variables declared inside functions.

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
