JavaScript has a number formatter (part of the Internationalization API).
// Create our number formatter.
var formatter = new Intl.NumberFormat('en-US', {
style: 'currency',
currency: 'USD',
// These options are needed to round to whole numbers if that's what you want.
//minimumFractionDigits: 0, // (this suffices for whole numbers, but will print 2500.10 as $2,500.1)
//maximumFractionDigits: 0, // (causes 2500.99 to be printed as $2,501)
});
formatter.format(2500); /* $2,500.00 */
Use undefined
in place of the first argument ('en-US'
in the example) to use the system locale (the user locale in case the code is running in a browser). Further explanation of the locale code.
Here's a list of the currency codes.
Intl.NumberFormat vs Number.prototype.toLocaleString
A final note comparing this to the older .toLocaleString
. They both offer essentially the same functionality. However, toLocaleString in its older incarnations (pre-Intl) does not actually support locales: it uses the system locale. So when debugging old browsers, be sure that you're using the correct version (MDN suggests to check for the existence of Intl
). There isn't any need to worry about this at all if you don't care about old browsers or just use the shim.
Also, the performance of both is the same for a single item, but if you have a lot of numbers to format, using Intl.NumberFormat
is ~70 times faster. Therefore, it's usually best to use Intl.NumberFormat
and instantiate only once per page load. Anyway, here's the equivalent usage of toLocaleString
:
(2500).toLocaleString('en-US', {
style: 'currency',
currency: 'USD',
}); /* $2,500.00 */
Some notes on browser support and Node.js
- Browser support is no longer an issue nowadays with 98% support globally, 99% in the US and 99+% in the EU
- There is a shim to support it on fossilized browsers (like Internet Explorer 8), should you really need to
- Node.js before v13 only supports
en-US
out of the box. One solution is to install full-icu, see here for more information

The # symbol identifies the ID of the element. Use .text() to set the inner text.
$('div#printdirec').text('tttt');

In the toolbar in the bottom right corner you will see a item that looks like the following: After clicking on it you will get the option to indent using either spaces or tabs. After selecting your indent type you will then have the option to change how big an indent is. In the case of the example above, indentation is set to 4 space characters per indent. If tab is selected as your indentation character then you will see Tab Size instead of Spaces
If you want to have this apply to all files and not on an idividual file basis, override the
Editor: Tab Size
andEditor: Insert Spaces
settings in either User Settings or Workspace Settings depending on your needsEdit 1
To get to your user or workspace settings go to Preferences -> Settings. Verify that you are on the User or Workspace tab depending on your needs and use the search bar to locate the settings. You may also want to disable
Editor: Detect Indentation
as this setting will override what you set forEditor: Insert Spaces
andEditor: Tab Size
when it is enabled
