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

To use the upperFirst function from the lodash library in TypeScript, follow these steps:

1. Install the lodash library using a package manager such as npm:

   index.ts
   npm install lodash
   19 chars
   2 lines

2. Import the upperFirst function from the lodash library:

   index.ts
   import { upperFirst } from "lodash";
   37 chars
   2 lines

3. Use the upperFirst function to capitalize the first letter of a string:

   index.ts
   const myString = "hello world";
   const myCapitalizedString = upperFirst(myString);
   console.log(myCapitalizedString); // "Hello world"
   133 chars
   4 lines

4. Optionally, you can specify the locale as the second argument of the upperFirst function:

   index.ts
   const myString = "ßümpflîz";
   const myCapitalizedString = upperFirst(myString, "tr");
   console.log(myCapitalizedString); // "SSümpflîz"
   134 chars
   4 lines

   In this example, the locale is set to Turkish ("tr") which has specific rules for capitalizing certain letters.

Note: Make sure to include the lodash library in your TypeScript project's build process, either through a bundler or by importing it in your HTML file.
