Lodash _.toLower



The lodash _.toLower method is a utility method in the lodash library used to convert a provided string value to lowercase. It returns a new string with all the characters in the original string converted to lowercase.




The _.toLower method accepts a single string parameter which is the string value to be converted to lowercase.

Return Value:

The _.toLower method returns a new string value with all the characters in the provided string value converted to lowercase.


Here are some examples of the _.toLower method in action:

// Using the _.toLower method on a simple string const originalString = "HELLO WORLD"; const lowerCaseString = _.toLower(originalString); // "hello world" console.log(lowerCaseString);

// Using the _.toLower method on a more complex string const complexString = "ThIs iS a VeRy CoMpLeX STRIng!"; const newString = _.toLower(complexString); // "this is a very complex string!" console.log(newString);

In both examples, the original string value is passed to the _.toLower method and the returned value is a new string with all the characters converted to lowercase.


The _.toLower method is a useful utility method when dealing with strings in JavaScript. It is important to note that the method only converts to lowercase and does not handle any other transformation.

This method is highly performant and is recommended in place of the built-in JavaScript toLowerCase() method when working with multiple strings or large strings.


Overall, the lodash _.toLower method is an efficient and reliable utility method used to convert a provided string value to lowercase. It can be highly beneficial in numerous use-cases, especially when working with multiple strings in JavaScript.
