care ar fi echivalentul ampersantului in javascript

Buna ziua !!!
Astazi invatam javascript si tocmai ce ajunsesem la functii si eu fiind objnuit cu c++ ,pentru ca sunt pe mate-info si acesta este limbajul pe care il studiez , ma tot intrebam care ar fi echivalentul ampersantului in javascript . Mai exact cand creez o functie in c++ si pun un parametru acesta nu va modifica valoarea intiala a variabilei dar daca pun ampersant in fata atunci se schimba.
Intrebarea este :Exista vreun echivalent pentru asta in javascript???

Buna ziua,

"pentru ca suntem" pe un forum avem arie dedicata programarii, inclusiv JS
https://forum.softpe...ting-languages/

https://stackoverflo...nce-vs-by-value

Nu exista echivalent, in Javascript valorile sunt pasate mereu ca valoarea (nu ca referinta), mai putin cand valoarea nu este o primitiva. Daca nu este o primitiva (ex: este un obiect, vector, functie), atunci el va fi pasat mereu ca referinta.

Iar in cazul in care operatorul & era folosit pentru returnarea adresei de memorie a variabiliei: nu exista echivalent pentru ca in Javascript nu poti sa afli adresa de memorie a unei variabile (daca ai putea ar prezenta un risc mare de securitate).
