Sometimes, we want to fill a JavaScript object literal with many static key/value pairs efficiently.
In this article, we’ll look at how to fill a JavaScript object literal with many static key/value pairs efficiently.
How to fill a JavaScript object literal with many static key/value pairs efficiently?
To fill a JavaScript object literal with many static key/value pairs efficiently, we create a map.
For instance, we write
const map = new Map([
["key1", "value1"],
["key2", "value2"],
]);
const value = map.get("key1");
to call the Map constructor with an array of key-value pair arrays to create a map.
Then we get the value by the get with 'key1'.
Conclusion
To fill a JavaScript object literal with many static key/value pairs efficiently, we create a map.
