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

To use the conforms function from the Lodash library in TypeScript, follow the steps below:

  1. First, make sure to install the Lodash library and its types:

    index.ts
    npm install lodash @types/lodash
    
    33 chars
    2 lines

    This installs the Lodash library and its TypeScript definitions.

  2. Then, import the conforms function from the Lodash library:

    index.ts
    import { conforms } from 'lodash';
    
    35 chars
    2 lines
  3. Next, define a type for the object you want to test using the conforms function. For example, let's say you want to test if an object has a name property that is a string and an age property that is a number. You can define the following type:

    index.ts
    interface Person {
      name: string;
      age: number;
    }
    
    52 chars
    5 lines
  4. Finally, you can use the conforms function to test if an object conforms to the type you defined. For example:

    index.ts
    const isPerson = conforms({
      name: (val) => typeof val === 'string',
      age: (val) => typeof val === 'number',
    });
    
    const person1: Person = { name: 'Alice', age: 25 };
    const person2 = { name: 'Bob', age: '30' };
    
    console.log(isPerson(person1)); // true
    console.log(isPerson(person2)); // false
    
    294 chars
    11 lines

    The conforms function returns a function that takes an object as its parameter and returns a boolean that indicates whether the object conforms to the type you defined. In this example, isPerson is a function that takes an object with a name property that is a string and an age property that is a number, and returns true if the object satisfies the requirement, and false otherwise.
