lt (Lodash Compatibility)

Use the < operator instead

This lt function performs slower due to additional processing like toNumber function calls and string type checking.

Instead, use the faster and more modern < operator.

Checks if value is less than other.

const result = lt(value, other);

Reference

lt(value, other)

Use lt when you want to compare two values to check if the first value is less than the second. Strings are compared lexicographically, and other types are converted to numbers for comparison.

import { lt } from 'es-toolkit/compat';

lt(1, 3);
// Returns: true

lt(3, 3);
// Returns: false

lt(3, 1);
// Returns: false

// String comparison (lexicographical)
lt('abc', 'def');
// Returns: true

lt('def', 'abc');
// Returns: false

// Other types are converted to numbers for comparison
lt('5', 10);
// Returns: true (5 < 10)

lt(null, 1);
// Returns: true (0 < 1)

Parameters

• value (unknown): The first value to compare.
• other (unknown): The second value to compare.

Returns

(boolean): Returns true if the first value is less than the second, false otherwise.
