How to use the constantCase function from change-case

change-case.constantCase is a function that converts a string to a constant-case string, where words are separated by underscores and all letters are capitalized.

How does change-case.constantCase work?

The change-case.constantCase function is a part of the change-case library, which provides functions for converting strings between different cases. The constantCase function takes a string as input and returns a new string that is converted to constant-case format. In constant-case format, all letters are capitalized and words are separated by underscores. For example, the string "helloWorld" would be converted to "HELLO_WORLD" using the constantCase function. Here is an example of how to use the change-case.constantCase function in JavaScript: javascript Copy code {{{{{{{ const changeCase = require('change-case'); const myString = 'someVariableName'; const constantCaseString = changeCase.constantCase(myString); console.log(constantCaseString); // outputs "SOME_VARIABLE_NAME" In this example, we first require the change-case library using require(). We then define a string variable myString that contains a variable name in camelCase format. We then use the change-case.constantCase function to convert myString to constant-case format and store the result in the constantCaseString variable. Finally, we log the constantCaseString variable to the console to verify that the conversion worked as expected. Overall, the change-case.constantCase function provides a simple and convenient way to convert a string to constant-case format in JavaScript.

const changeCase = require("change-case");

const myString = "This is a sample string";
const constantCaseString = changeCase.constantCase(myString);

console.log(constantCaseString); // outputs "THIS_IS_A_SAMPLE_STRING"

In this example, we first require the change-case library using require(). We then define a string variable myString that contains a sample string. We then use the change-case.constantCase function to convert myString to constant-case format and store the result in the constantCaseString variable. Finally, we log the constantCaseString variable to the console to verify that the conversion worked as expected. Overall, this example demonstrates how to use the change-case.constantCase function to convert a string to constant-case format in JavaScript.
