lodash.padstart

What is lodash.padstart?

The lodash.padstart package is a utility function from the Lodash library that pads the beginning of a string with a specified character until the string reaches a given length. This is useful for formatting strings to ensure they have a consistent length, which can be important for tasks like aligning text in console output or preparing data for display.

What are lodash.padstart's main functionalities?

Basic Padding

Pads the beginning of the string 'abc' with spaces until the total length is 6.

const _ = require('lodash.padstart');
const result = _.padStart('abc', 6);
console.log(result); // '   abc'

Padding with Custom Character

Pads the beginning of the string 'abc' with the character '0' until the total length is 6.

const _ = require('lodash.padstart');
const result = _.padStart('abc', 6, '0');
console.log(result); // '000abc'

Padding with Multiple Characters

Pads the beginning of the string 'abc' with the sequence '_-' until the total length is 8.

const _ = require('lodash.padstart');
const result = _.padStart('abc', 8, '_-');
console.log(result); // '_-_-abc'

left-pad

The left-pad package provides similar functionality to lodash.padstart by padding the beginning of a string with a specified character or sequence until it reaches a given length. It is simpler and more focused solely on padding strings, whereas lodash.padstart is part of the larger Lodash utility library.

string.prototype.padstart

The string.prototype.padstart package is a polyfill for the native String.prototype.padStart method introduced in ECMAScript 2017. It provides the same functionality as lodash.padstart but is designed to add this method to the String prototype for environments that do not support it natively.
