This article demonstrates trimEnd and trimRight methods of JavaScript string. Both methods are used to perform the same task and their implementation is shown below:
JavaScript trimStart() method:The trimStart() method in JavaScript is used to remove whitespace from the beginning of a string. The value of the string is not modified in any manner, including any whitespace present after the string.
Syntax:string.trimStart();Return Value:
It returns the final string that is stripped out of all the white space in the beginning.
Example: This example implements the trimStart() method.
JavaScript
// Function to implement trimStart method
function trimString() {
// Input strings
str1 = " GeeksforGeeks ";
str2 = "Hello There! ";
// Implementation of trimStart method
trimmed_out = str1.trimStart();
trimmed_out2 = str2.trimStart();
// Display output
console.log('"' + trimmed_out + '"');
console.log('"' + trimmed_out2 + '"');
}
// Function call
trimString()
"GeeksforGeeks " "Hello There! "JavaScript trimLeft() method:
The trimStart() method has an alias which is the trimLeft() method. It performs exactly the same function as the trimStart() method.
Syntax:string.trimLeft();Return Value:
It returns the final string that is stripped out of all the white space in the beginning.
Example: This example implements the trimLeft() method.
JavaScript
// Function to implement trimLeft method
function trimString() {
// Input strings
str1 = " GeeksforGeeks ";
str2 = "Portal ";
// Implementation of trimLeft method
trimmed_out = str1.trimLeft();
trimmed_out2 = str2.trimLeft();
// Display output
console.log('"'
+ trimmed_out + '"');
console.log('"'
+ trimmed_out2 + '"');
}
// Function call
trimString()
"GeeksforGeeks " "Portal "
