I am working on a filter for an e-commerce project.
It has an active filters section, where the filters that are active are displayed and can be made inactive. This function works, correctly finds the index and removes the right object. I used some of the same code to create the function that toggles a filters active status, but for some reason it just constantly returns -1 even though the console log shows the object in the array, and shows the object being exactly the same. I am so confused.
Here's the console log of the array:
[
{
"section": "Section 1",
"option": "Option 1"
},
{
"section": "Filter Section",
"option": "Option 1"
},
{
"section": "Section 1",
"option": "Option 2"
}
]
Here's the console log of the object i am trying to find the index of:
{
"section": "Filter Section",
"option": "Option 1"
}
And then the console is logging -1 for the index, when it should clearly be 1.
Here's the code:
