Strings are one of the different datatypes in JavaScript. They are mainly helpful in managing data within this programming language. However, some strings are not stored desirably. For example, unnecessary characters might appear within a string, such as whitespaces. Though some whitespaces are helpful within a string, some unnecessary ones might appear before or after the string. This is the point where trimEnd in JavaScript comes to the rescue. In this brief article, our Java Programmers elaborate on what trimEnd in JavaScript is and how to apply it to overcome all string headaches. They also help students with their JavaScript assignments and projects.
What is Trimend in JavaScript?
The trimEnd() method is a JavaScript technique for removing white spaces from the end of a string. White space characters include spaces, tabs, and the carriage return. The technique to does not modify the value of the string in any way, which also includes any white space present before the string. Below is the standard syntax used in removing white spaces:
| String.trimEnd() |
Return Value: The above syntax returns the final string that has removed all the white spaces at the end.
Code Example
| var example_string = ” This is the example string \t”; console.log(`With trailing white-spaces: “`+example_string+ `”`); console.log(`Without trailing white-spaces: “`+example_string.trimEnd()+ `”`); |
The above code is a typical illustration of how one can use the trimEnd() method. From this example, one can notice the string without trailing white spaces lacks white spaces to its right, while there is preservation of white spaces on the left.
Alternative to Trimend
Again, there is an alternative to the trimEnd() JavaScript technique that serves a similar purpose. This is the JavaScript trimRight() method. It operates with the same principle of the trimEnd(). Below is the syntax for this technique:
| String.trimRight() |
Return Value: The above syntax returns the final string stripped out of all the white spaces at the end. Below is an example illustrating the trimRight() method.
JavaScript Example
| // Function to implement trimRight method function trimString() { // Imput Strings str1 = ” GeeksforGeeks “; str2 = ” Portal “; // Implementing trimRight method trimmed_out = str1.trimRight(); trimmed_out2 = str2.trimRight(); // Display output console.log(‘”‘ + trimmed_out + ‘”‘); console.log(‘”‘ + trimmed_out2 + ‘”‘); } // Function call trimString(); |
Output
The output from this example will be as follows:
| ” GeeksforGeeks” ” Portal” |
How to Remove Whitespaces in Your JavaScript?
1. Use trimEnd in Javascript
For various reasons, you are likely to encounter the following strings within your application:
“fly better with emirates” and may need to reduce it to only the most relevant characters. Accordingly, the final string should read “fly better with Emirates”. Applying the trimEnd technique helps remove these unnecessary white spaces at the end of the string.
But how does the trimEnd method remove whitespace at the end of the string? Below is an example:
| const str = ” fly better with Emirates “; const newStr = str.trimEnd(); console.log(newStr); |
The output will be as follows:
| fly better with Emirates |
This output shows there is no whitespace at the end of the string. However, a whitespace still exists at the beginning of the string.
2. Use trimStart
The process of removing whitespace at the beginning of the string requires another method. This is where the trimStart approach becomes applicable. Applying the same example, the initial script will look like this:
| const str = ” fly better with Emirates “; const newStr = str.trimEnd().trimStart(); console.log(newStr); |
However, its output will be as follows:
| fly better with Emirates |
In this final output, there is no more whitespace at the beginning of the string. However, there is a more comprehensive approach to removing all whitespaces with a straightforward command. Accordingly, this brings us to the third option: the trim command.
3. Use trim
The trim method is ideal for removing whitespaces at the beginning and end of the string. For example, using the same example as above, the string will read like this:
| const str = ” fly better with emirates “; const newStr = str.trim(); console.log(newStr); |
The output will read like this:
| fly better with Emirates |
What’s Next with String Headaches?
Whitespace characters can be very annoying in the code. With these three options, you can easily remove them on your own. The trimEnd in javascript helps remove whitespace from the string end, while trimStart removes whitespace in the string start. The trim method is ideal for removing spaces at both ends.
