lowerFirst (Lodash compatibility)

Use lowerFirst from es-toolkit

This lowerFirst function operates slower due to handling non-string input values.

Instead, use the faster and more modern lowerFirst from es-toolkit.

Converts the first character of a string to lowercase.

const result = lowerFirst(str);

Reference

lowerFirst(str)

Converts the first character of a string to lowercase. The remaining characters are kept as is. This is useful for creating camelCase variable names or when you only want to lowercase the first character.

lowerFirst('fred'); // 'fred'
lowerFirst('Fred'); // 'fred'
lowerFirst('FRED'); // 'fRED'
lowerFirst(''); // ''

Non-string values are also converted to strings before processing.

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

lowerFirst(123); // '123'
lowerFirst(null); // ''
lowerFirst(undefined); // ''
