how to use the ismap function from the lodash library in typescript

To use the ismap function from the lodash library in TypeScript, you need to install the lodash library as a dependency in your TypeScript project with:

npm install lodash --save

2 lines

Then, you can import and use the ismap function from the lodash package:

index.ts
import { isMap } from 'lodash';

const myMap = new Map();

console.log(isMap(myMap)); // true
console.log(isMap({})); // false

The ismap function takes a single argument and returns a boolean value indicating whether the argument is of type Map<any, any>.

Type inference in TypeScript will automatically detect the type of the argument passed to ismap and will provide you with helpful error messages if the argument is not of type Map<any, any>.

Using the ismap function is one example of functional programming in TypeScript, which focuses on writing code based on pure functions that do not mutate state or have side effects.
