ViewsfindIndex method is not retrieving the index while the value exist
I'm trying to find the index of an object in an array.
for (let i = 0; i < sitesDeTir.length; i++) {
let affIndex = affectations.findIndex((aff) => aff.id_sdt === sitesDeTir[i].id);
if (affIndex === -1) {
// action
} else {
// action
}
}
When I use the Chrome debugger, I can see that sitesDeTir[i].id is equal to 371 (number). I've also digged in the array (called affectations) and I see that there is an object who have id_sdt to 371 (number) but I always receive -1.
What I'm a missing here? I'm sorry for the link, I don't have enough reputation to embed it in the post.

The problem occurs because you compare apples with bananas :-) Write id_SDT instead id_sdt.
for (let i = 0; i < sitesDeTir.length; i++) {
let affIndex = affectations.findIndex((aff) => aff.id_SDT === sitesDeTir[i].id);
if (affIndex === -1) {
// action
} else {
// action
}
}
