How to merge two Maps in TypeScript

In Typescript, do you want to combine two maps? In this tutorial, I cover every Typescript merge map. We will look into a few different methods to integrate TypeScript maps with complete code.de.

What is TypeScript Maps?

Similar to an Object, a Map in Typescript is a grouping of keyed data items. Maps, on the other hand, support any kind of key. Strong typing is provided by TypeScript for these collections, which improves code reliability.

TypeScript

const map1 = new Map([["a", 1], ["b", 2]])
const map2 = new Map([["c", 1], ["d", 2]])
const mergedMap = new Map([...map1.entries(), ...map2.entries()])
console.log(mergedMap); 

Ouput:

{ 'a' => 1, 'b' => 2, 'c' => 1, 'd' => 2 }

OR

const map1 = new Map([['name', 'techstackkit.com']]);
const map2 = new Map([['age', 24]]);
const mergedMap = new Map([...map1, ...map2]);
console.log(mergedMap); 

Ouput:

{ 'name' => 'techstackkit.com', 'age' => 30 }

Happy Coding! ❤️
