I have some enum objects and i want to get its lebel by it's value.
Let's say this is my enum list
const enumList = {
businessType: [
{ value: "b", label: "B2B" },
{ value: "s", label: "SAAS" },
{ value: "c", label: "C2C" },
],
userType: [
{ value: "A", label: "Admin" },
{ value: "s", label: "Super User" },
{ value: "t", label: "trainer" },
]
}
So now I want to get a particular object label by its key.
like this,
enumList.userType.getLabel('s')'
// super user
I mean, i want to make it re-usable, currently i am doing like this and i dont like it
index = enumList.userType.findIndex(x => x.value ==="s");
enumList.userType[index].label
// super user
Does anyone know how can i make it re-usable to access it from globally like this enumList.userType.getLabel('s) ?
See Why is extending native objects a bad practice?
It looks like you want a one-liner, so just use find
const { label } = enumList.userType.find(userType => userType.value === 's');
This custom Array method will allow you to do this enumList.userType.getLabel('s') and receive 'Super User'
Array.prototype.getLabel = function(val) {
return this.find(({value}) => value === val).label
}
