I have a quite simple JavaScript object, which I use as an associative array. Is there a simple function allowing me to get the key for a value, or do I have to iterate the object and find it out manually?
function getKeyByValue(object, value) {
return Object.keys(object).find(key => object[key] === value);
}
ES6, no prototype mutations or external libraries.
Example,
function getKeyByValue(object, value) {
return Object.keys(object).find(key => object[key] === value);
}
const map = {"first" : "1", "second" : "2"};
console.log(getKeyByValue(map,"2"));Collected from the Internet
