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 methodfunction trimString() { // Input strings str1 = " neveropen "; 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 calltrimString() |
"neveropen " "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 methodfunction trimString() { // Input strings str1 = " neveropen "; 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 calltrimString() |
"neveropen " "Portal "
