i have a JSON object (sent from php) and I want to convert the IDs to a numeric key using JS. So currently it looks something like that:
let foo = {"66":"test","65":"footest"};
And now I want it to look like this:
let foo = {66:"test",65:"footest"};
Object keys do not need to be numerical to be accessed - as noted in the comments - they are strings regardless.- Below, I am console logging the "66" property using the brackets notation - foo[66]
let foo = {"66":"test","65":"footest"};
console.log(foo[66]); // gives "test"
// if you want to assign values numerically - ie using the index of a loop - then you could do
for(i = 63; i<65; i++) {
foo[i] = "test" + i;
}
console.log(foo); // gives {"63": "test63", "64": "test64","65": "footest","66": "test"}
