How does lodash.snakeCase work?

lodash.snakeCase is a method that takes a string as its input and returns a new string that represents the input string in snake case. Snake case is a naming convention in which words are separated by underscores and all letters are lowercase. The method works by first replacing all non-word characters (e.g., punctuation marks) in the input string with spaces. It then splits the resulting string into words based on the space character, and converts each word to lowercase. Finally, it joins the words together using underscores to create the final snake case string. Here's a more detailed breakdown of the steps involved: Replace non-word characters with spaces: Any characters in the input string that are not letters, digits, or underscores are replaced with spaces. For example, "Hello, world!" would become "Hello world ". Split the string into words: The string is split into an array of words using the space character as the delimiter. For example, "Hello world " would become ["Hello", "", "world", ""]. Convert each word to lowercase: Each word in the array is converted to lowercase using the toLowerCase method. For example, ["Hello", "", "world", ""] would become ["hello", "", "world", ""]. Join the words together with underscores: The array of lowercase words is joined together into a single string using underscores as the separator. For example, ["hello", "", "world", ""] would become "hello__world_". Remove extra underscores: Any consecutive underscores in the final string are collapsed into a single underscore. For example, "hello__world_" would become "hello_world". By following these steps, lodash.snakeCase is able to convert any input string into snake case.

const _ = require("lodash");

const myString = "Convert this string to snake case";
const snakeCaseString = _.snakeCase(myString);

console.log(snakeCaseString);
// Output: "convert_this_string_to_snake_case"

In this example, the lodash.snakeCase method is used to convert the string "Convert this string to snake case" to snake case. The resulting string "convert_this_string_to_snake_case" is then logged to the console. Note that lodash.snakeCase is part of the lodash library, so we first need to import the lodash library and assign it to a variable (in this case, _). We can then call the _.snakeCase method to convert the string to snake case.
