The purpose of string padding is to add characters to a string, so it reaches a specific length.
padEnd(), introduced in ES2017, adds such characters at the end of the string.
padEnd(targetLength [, padString])
Sample usage:
| padEnd() | |
|---|---|
| ‘test’.padEnd(4) | ‘test' |
| 'test’.padEnd(5) | ‘test ' |
| 'test’.padEnd(8) | ‘test ' |
| 'test’.padEnd(8, ‘abcd’) | ‘testabcd’ |
