indentString

TS JS Deno

Indents each line in the provided string.

Use String.replace and a regular expression to add the character specified by indent count times at the start of each line. Omit the third parameter, indent, to use a default indentation character of ' '.

typescript
const indentString = (str: string, count: number, indent = " ") => {
  indent = indent.repeat(count);
  return str.replace(/^/gm, indent);
};
typescript
indentString("Lorem\nIpsum", 2); // '  Lorem\n  Ipsum'
indentString("Lorem\nIpsum", 2, "_"); // '__Lorem\n__Ipsum'
