Lodash _.repeat() Method

What You’ll Learn

By the end of this tutorial, you’ll use Lodash’s _.repeat() confidently in real string workflows.

What Is _.repeat()?

_.repeat() returns a new string by repeating the input n times. It is ideal for generating visual separators, placeholder patterns, and repeated markup fragments without manual loops.

📝 Syntax

_.repeat(string, [n=1])

Syntax Rules

• string — The string to repeat.
• n — Repeat count (non-negative integer; default 1).
• Return value — Concatenated result string.
• n = 0 — Returns empty string.
• Empty input — Repeating empty string returns empty string.

import repeat from "lodash/repeat";

const border = repeat("-", 40);
// -> "----------------------------------------"

Practical _.repeat() patterns with copy-ready code and interactive Try It Yourself labs.

const repeated = _.repeat("Hello ", 3);
console.log(repeated);
// -> "Hello Hello Hello "

Hello Hello Hello 

const border = _.repeat("-", 20);
console.log(border);
// -> "--------------------"

--------------------

const items = _.repeat("<li>Item</li>\n", 3);
console.log("<ul>\n" + items + "</ul>");

<ul>
<li>Item</li>
<li>Item</li>
<li>Item</li>
</ul>

console.log(_.repeat("Hello", 0));
// -> ""

(empty string)

function safeRepeat(str, n) {
  if (!Number.isInteger(n) || n < 0) return "";
  return _.repeat(str, n);
}
console.log(safeRepeat("x", 5));

xxxxx

const str = "-";
const native = str.repeat(20);
const lodash = _.repeat(str, 20);
// both -> "--------------------"

Both approaches yield 20 dashes

📝 Notes

• _.repeat() returns an empty string when n is 0.
• Repeating an empty string always returns ''.
• For very long repetitions, native String.repeat() may be faster.
• Validate n is a non-negative integer for user input.
• Strings are immutable.
• Native '-'.repeat(20) is equivalent in ES2015+.
