Lodash _.trimEnd() Method

What You’ll Learn

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

What Is _.trimEnd()?

_.trimEnd() strips characters from the end of a string while leaving the beginning untouched. It is ideal when leading spaces are meaningful—indented log lines, aligned columns, or prefixed markers—and you only need to clean trailing noise.

📝 Syntax

_.trimEnd(string, [chars])

Syntax Rules

• string — The input string.
• chars — Optional characters to remove from the end (default: whitespace).
• Return value — New string with trailing matches removed.
• Alias — _.trimRight is the same function.

import trimEnd from "lodash/trimEnd";

const line = "   Hello, World!    ";
const result = trimEnd(line);
// -> "   Hello, World!"

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

const line = "   Hello, World!    ";
const trimmed = _.trimEnd(line);

console.log(JSON.stringify(trimmed));
// -> "   Hello, World!"

"   Hello, World!"

const email = "user@example.com   ";
const safe = _.trimEnd(email);

console.log(safe);
// -> "user@example.com"

safe: user@example.com

const rows = ["alpha  ", "beta	", "gamma"];
const clean = rows.map(_.trimEnd);
// -> ["alpha", "beta", "gamma"]

["alpha", "beta", "gamma"]

const label = "Loading...";
const plain = _.trimEnd(label, ".");
// -> "Loading"

plain: Loading

const entry = "[INFO] Task complete    ";
const clean = _.trimEnd(entry);
// -> "[INFO] Task complete"

clean: [INFO] Task complete

const line = "  hi  ";
const native = line.trimEnd();
const lodash = _.trimEnd(line);
// both -> "  hi"

Both approaches yield: "  hi" (leading spaces kept)

📝 Notes

• _.trimEnd() affects only the end of the string.
• _.trimRight is an alias for the same function.
• Pass chars to trim specific trailing characters.
• Use _.trimStart() for the opposite side.
• Use _.trim() when both ends need cleaning.
• Native trimEnd() is available in ES2019+.
