Pad string
Pads a string on both sides with the specified character, if it's shorter than the specified length.
- Use
String.prototype.padStart()andString.prototype.padEnd()to pad both sides of the given string. - Omit the third argument,
char, to use the whitespace character as the default padding character.
const pad = (str, length, char = ' ') => str.padStart((str.length + length) / 2, char).padEnd(length, char); pad('cat', 8); // ' cat ' pad(String(42), 6, '0'); // '004200' pad('foobar', 3); // 'foobar'
