The padEnd() function accepts a string argument and returns that string padded by a provided padding string, until a desired final string length is reached.
padEnd(string, targetLength, paddingString)
string.padEnd(targetLength, paddingString)
Code language: JavaScript (javascript)Note that targetLength is the length of the final output string, which includes the repeated paddingString and the input string.
padEnd (and its counterpart, padStart), are useful for ensuring that input strings of varying lengths conform to a single target length.
Example Formulas
"hello".padEnd(8, ".") /* Output: "hello..." */
"hello".padEnd(10, ".") /* Output: "hello....." */
"Well hello there".padEnd(1, ".") /* Output: "Well hello there" (if the input string is longer than targetLength, the input string is returned alone and untruncated */
