## Usage
|

|
|

|
|

||
|
|
const leftPad = require("left-pad");
|
||
|
|
|
||
|
|

|
||
|
|
// => " foo"
|
||

|
||
|

|
||
|
|
|
||
|
|
leftPad(1, 2, "0");
|
||
|

|
||
|
|

**NOTE:** The third argument should be a single `char`. However the module
|
||
|
|
doesn't throw an error if you supply more than one `char`s. See
|
||
|
|
[#28](https://github.com/stevemao/left-pad/pull/28).

|
**NOTE:** Characters having code points outside of
|
||
|
|
[BMP plan](https://en.wikipedia.org/wiki/Plane_(Unicode)#Basic_Multilingual_Plane)
|
||
|
|
are considered a two distinct characters. See
|
||
|
|
[#58](https://github.com/stevemao/left-pad/issues/58).
