Using the Trim String Method in JavaScript

The String.trim method is used to remove the whitespace from both ends of a string.

• Parameters: It does not accept any parameter.
• Return type: It returns the string without whitespace.

An example of how to use it is shown below 🙈

let reptilianString = "     🐊🐊🐊🐊     ";

console.log(reptilianString.trim());

// 🐊🐊🐊🐊

If we want to remove the whitespace only from the front but not from rear or vice-versa, we can also use the following methods.

• trimStart()
• trimEnd()

trimStart()

The trimStart() method is used to remove whitespace from the start of a string.

• Parameters: It does not accept any parameter.
• Return type: It returns the string without whitespace at the start.

trimEnd()

The trimEnd() method is used to remove the whitespace from the right end of the string.

Parameters: It does not accept any parameter. Return type: It returns the string without whitespace on the right end.
