Lodash _.trim


The lodash _.trim method is a utility function that removes leading and trailing whitespace from a string. It is part of the popular Lodash library, which provides many useful functions for working with data in JavaScript.

This method takes a single argument, which is the string to be trimmed. It then returns a new string with all leading and trailing whitespace removed. Whitespace includes spaces, tabs, newlines, and other non-printable characters.

For example, consider the following code:

const str = '  Hello, World!  ';
const trimmedStr = _.trim(str);
console.log(trimmedStr); // 'Hello, World!'

As you can see, the _.trim method removed the two spaces at the beginning and end of the string, resulting in a trimmed string of "Hello, World!".

One important thing to note is that the _.trim method does not modify the original string. Instead, it returns a new string with the whitespace removed. This is important to keep in mind if you need to preserve the original string.

In addition to _.trim, the Lodash library provides several related methods for working with whitespace, including _.trimStart (which removes only leading whitespace), _.trimEnd (which removes only trailing whitespace), _.trimLeft (an alias for _.trimStart), and _.trimRight (an alias for _.trimEnd).

Overall, the _.trim method is a powerful and versatile utility function that can help simplify working with strings in JavaScript.
