Lodash _.toUpper

Overview

The lodash _.toUpper method is a utility function that helps convert a given string to uppercase letters. This method is a member of lodash, which is a popular JavaScript utility library that provides many useful functions for everyday programming. The _.toUpper function is often used in web development, data processing, and other programming applications where data needs to be standardized or transformed.

Here is the syntax for the _.toUpper method:

_.toUpper([string=''])

The _.toUpper method takes an optional string parameter that represents the input string to be converted to uppercase letters. If no string is provided, the method returns an empty string. If string is not a string data type, the method tries to convert it to a string using _.toString.

Here is an example of using the _.toUpper method to convert a string to uppercase:

_.toUpper('hello world');
// returns 'HELLO WORLD'

The _.toUpper method returns a new string that contains the same characters as the original string but in uppercase letters. The original string is not modified.

One thing to note is that the _.toUpper method doesn't distinguish between uppercase and lowercase letters. It will convert all letters in the input string to uppercase, regardless of their original case. This can be useful for standardizing data or making it easier to compare strings without worrying about case sensitivity.

In summary, the lodash _.toUpper method is a useful utility function for converting a string to uppercase letters. It is part of the lodash library, which provides many other useful functions for data processing and web development. The method takes an optional input string parameter and returns a new string containing the input string converted to uppercase.
