E ala i le JavaScript

Valaau ma le lima le carousel ma:

const carousel = new bootstrap.Carousel('#myCarousel')

Filifiliga

A'o mafai ona pasia filifiliga e ala i fa'amatalaga uiga po'o le JavaScript, e mafai ona e fa'aopoopoina se igoa filifiliga i le data-bs-, pei o le data-bs-animation="{value}". Ia mautinoa e sui le ituaiga mataupu o le igoa filifiliga mai le " CamelCase " i le " kebab-case " pe a pasia filifiliga e ala i faʻamatalaga uiga. Mo se faʻataʻitaʻiga, faʻaaoga data-bs-custom-class="beautifier"nai lo le data-bs-customClass="beautifier".
