Lodash _.upperFirst

Overview

The lodash _.upperFirst method is a utility function that is used to capitalize the first character of a given string. This method is a part of the popular Lodash library, which is a set of utility methods that provide functional programming workflows in JavaScript.

The _.upperFirst method accepts a single string argument, which is the string that needs to be capitalized. This method capitalizes the first character of the string and returns the modified string. If the input string is empty, this method returns an empty string.

Here is an example code snippet that demonstrates how to use the lodash _.upperFirst method:

const _ = require('lodash');

const str = 'hello, world!';
const upperStr = _.upperFirst(str);

console.log(upperStr); // Output: Hello, world!

In this example, we first import the lodash library using the require statement. We then define a string variable and pass it to the _.upperFirst method to capitalize the first character of the string. Finally, we log the modified string to the console.

The lodash _.upperFirst method is a simple but useful function that can save time and effort when working with strings in JavaScript. It is especially useful for formatting user input or generating display text in web applications.

Overall, the lodash _.upperFirst method is an excellent tool to have in your JavaScript utility belt, and its ease of use makes it a popular choice for many developers worldwide.
