In this article we will learn how to get an element from a map.
It is very common to get an element from a map in JavaScript.
Problem
Now we have a problem, which is that we want to get an element from a map.
Now let's define a map like this:
// Map
const map = new Map([
['name', 'John'],
['age', 30],
]);
console.log(map);
// Map(2) { 'name' => 'John', 'age' => 30 }
And we want to get an element from his key.
How to solve this problem?
Fortunately, we have a built-in function that get elements from the map called get
.
Get an element from a map using get
As we said before, we can use the get()
function to get an element from a map.
Example
// Map
const map = new Map([
['name', 'John'],
['age', 30],
]);
// Get element
const ele = map.get('name');
// Print element value
console.log(ele);
Output
John
map.get()
It takes the key and returns the value.
