This feature is well established and works across many devices and browser versions. It’s been available across browsers since April 2017.
The padEnd() method of String values pads this string with a given string (repeated and/or truncated, if needed) so that the resulting string has a given length. The padding is applied from the end of this string.
const str1 = "Breaded Mushrooms"; console.log(str1.padEnd(25, ".")); // Expected output: "Breaded Mushrooms........" const str2 = "200"; console.log(str2.padEnd(5)); // Expected output: "200 "
padEnd(targetLength) padEnd(targetLength, padString)
targetLengthThe length of the resulting string once the current str has been padded. If the value is less than or equal to str.length, then str is returned as-is.
padString OptionalThe string to pad the current str with. If padString is too long to stay within targetLength, it will be truncated from the end. The default value is the space character (U+0020).
A String of the specified targetLength with padString applied at the end.
"abc".padEnd(10); // "abc " "abc".padEnd(10, "foo"); // "abcfoofoof" "abc".padEnd(6, "123456"); // "abc123" "abc".padEnd(1); // "abc"
