This chapter introduces how to work with strings and text in JavaScript.You can create simple strings using either single or double quotes:More advanced strings can be created using escape sequences:The Unicode escape sequences require at least four hexadecimal digits following New in ECMAScript 2015.
Example Input: 9809142333 Output: (980) 914-2333 Format phone number without country code.
CAUTION: if you edit this page, do not include any characters above U+FFFF, until MDN bug 857438 is fixed ( The best one in my opinion is to use the Number object, in a non-constructor context (without the newkeyword): This takes care of the decimals as well. values, because JavaScript treats primitive values as objects when executing If you don't specify it, JavaScript will not round the number.In JavaScript, a number can be a primitive value (typeof = number) or an

Because of this, JavaScript offers plenty of tools to parse various data types, allowing you to easily interchange the format of data.

Tutorials, references, and examples are constantly reviewed to avoid errors, but we cannot warrant full correctness of all content. Learn how you can effectively format the phone number in javascript. W3Schools is optimized for learning, testing, and training.

Using normal strings, you would have to use the following syntax in order to get multi-line strings:To get the same effect with multi-line strings, you can now write:In order to embed expressions within normal strings, you would use the following syntax:Now, with template literals, you are able to make use of the syntactic sugar making substitutions like this more readable:For example, there are actually two different sort orders in German, Some German words conjugate with extra umlauts, so in dictionaries it’s sensible to order ignoring umlauts (except when ordering words differing Get the latest and greatest from MDN delivered straight to your inbox.The newsletter is offered in English only at the moment.

methods and properties.All number methods can be used on any type of numbers (literals, variables, or expressions):A parameter defines the number of characters behind the decimal point:The parameter is optional. to convert variables to numbers:JavaScript global methods can be used on all JavaScript data types.These are the most relevant methods, when working with numbers:Trying to do arithmetic with a non-numeric string will result in Number properties belongs to the JavaScript's number object wrapper called The reference contains descriptions and examples of all Number properties and methods.If you want to report an error, or if you want to make a suggestion, do not hesitate to send us an e-mail:

If we use the constructor (new Number("1234")) it returns us a Number object instead of a number value, so pay attention. With Unicode code point escapes, any character can be escaped using hexadecimal numbers so that it is possible to use Unicode code points up to You should use string literals unless you specifically need to use a Characters whose Unicode scalar values are greater than U+FFFF (such as some rare Chinese/Japanese/Korean/Vietnamese characters and some emoji) are stored in UTF-16 with two surrogate code units each. Accessing the individual code units in such a string using brackets may have undesirable consequences such as the formation of strings with unmatched surrogate code units, in violation of the Unicode standard. For currency formatting, I used Number.prototype.toFixed() to convert a number to string to have always two decimal digits.. object (typeof = object).There are 3 JavaScript methods that can be used The toString() method returns a number as a string.

If you haven’t already created an account, you will be prompted to do so after signing in. For example, a string containing the single character U+1F600 "Emoji grinning face" will have length 2. Particularly, I'll be covering how to convert a Number to a String in this article.

Examples might be simplified to improve reading and basic understanding.
