Lodash _.trimEnd


lodash is a JavaScript utility library which provides a lot of helpful functions for developers to use. One such function is the _.trimEnd method, which allows developers to trim whitespace or a specific character from the end of a string.

The _.trimEnd function takes two parameters: the string to trim, and the character to trim (which is optional). If no character is specified, the whitespace at the end of the string will be trimmed.

This method is similar to the standard JavaScript trim() function, but instead of trimming whitespace from both ends of the string, it only removes it from the end.

Here is an example of how to use the _.trimEnd() method:

const string = '   hello   ';
const trimmedString = _.trimEnd(string);

console.log(trimmedString); // '   hello'

In this example, the whitespace at the end of the 'string' variable is trimmed, producing the trimmed string ' hello'.

If you want to trim a specific character from the end of a string, you can pass it as a second parameter to the function. Here is an example:

const string = 'hello-world-';
const trimmedString = _.trimEnd(string, '-');

console.log(trimmedString); // 'hello-world'

In this example, the '-' character is trimmed from the end of the 'string' variable, producing the trimmed string 'hello-world'.

Overall, the _.trimEnd method is a very useful utility for developers who need to remove whitespace or specific characters from the end of a string. It's a simple and efficient way to clean up user input or manipulate strings for various purposes.
