Lodash _.padEnd


The lodash _.padEnd method is a utility function that is used to pad a string on its right side with a specified character until it reaches a desired length. This method takes three arguments: the string to be padded, the length of the final padded string, and the character to use for padding (which defaults to a space if not provided).

This method is helpful in situations where you need to format a string to fit in a certain place, such as a table or a fixed-width output window. It can also be useful when outputting data that needs to be consistently formatted, such as phone numbers or postal codes.

To use the _.padEnd method, you simply pass in the string you want to pad, the desired length of the final string, and the optional character to use for padding. For example:

_.padEnd('hello', 10, '.');
// expected output: 'hello.....'

This would take the string 'hello' and add periods (.) to the end of it until it reaches a length of 10 characters.

If the padding character is not provided, it defaults to a space, like this:

_.padEnd('hello', 10);
// expected output: 'hello     '

In addition to working with standard strings, the _.padEnd method also works with Unicode characters. This means that it can be used to pad strings that contain non-ASCII characters.

Overall, the lodash _.padEnd method is a useful utility function for padding strings with a specified character on the right side. It is easy to use and works well in a variety of situations, making it a valuable addition to any developer's toolkit.
