How to use String padEnd method In Javascript
This approach uses the padEnd method to truncate a string to the specified length. The padEnd method pads the current string with another string until the resulting string reaches the given length. However, we can use this method to achieve truncation by padding with an empty string and then slicing the result.
Example:
// JavaScript function for
// truncating a string to a
// specific length using padEnd
function truncateString(str, maxLength) {
return str.padEnd(maxLength).slice(0, maxLength);
}
// Input string
const str = "gfg is a good place for growth";
// Desired length of a string
const maxLength = 20;
console.log(truncateString(str, maxLength));
Output
gfg is a good place
JavaScript Program to Truncate a String to a Certain Length
In this article, we are going to learn how can we truncate a string to a certain length. Truncating a string to a certain length in JavaScript means shortening a string so that it doesn’t exceed a specified maximum length. This can be useful for displaying text in user interfaces, such as titles or descriptions while ensuring that the text does not exceed a certain number of characters.
