Particularly, I'll be covering how to convert a Number to a String in this article.

Number is a wrapper object that can perform many operations. For example, a string containing the single character U+1F600 "Emoji grinning face" will have length 2. 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. Tutorials, references, and examples are constantly reviewed to avoid errors, but we cannot warrant full correctness of all content. 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. CAUTION: if you edit this page, do not include any characters above U+FFFF, until MDN bug 857438 is fixed (

See also Return the string in all lowercase or all uppercase, respectively.Template literals are enclosed by the back-tick (` `) (Any new line characters inserted in the source are part of the template literal. For currency formatting, I used Number.prototype.toFixed() to convert a number to string to have always two decimal digits.. In another article I'll also be covering how to convert a String to an Numberin JavaScript. In JavaScript, a number can be a primitive value (typeof = number) or an object (typeof = object).

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.
// x will be NaN (Not a Number) Watch out for separators between digits: In the case you need to parse a string with decimal separators, use Intl.NumberFormatinstead.
But with JavaScript, methods and properties are also available to primitive 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. values, because JavaScript treats primitive values as objects when executing

Independent of input format, JavaScript will (by default) output dates in full text string format: JavaScript ISO Dates ISO 8601 is the international standard for the representation of dates and times. If we use the constructor (new Number("1234")) it returns us a Number object instead of a number value, so pay attention.

Examples might be simplified to improve reading and basic understanding. 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. Now once we have our input ready we can format it in US phone format. Learn how you can effectively format the phone number in javascript. A protip by avsej about javascript. .parseInt() The base can be defined by adding prefixes to the numbers we want to parse: No prefix - … 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.

Example Input: 9809142333 Output: (980) 914-2333 Format phone number without country code.

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 You can create simple strings using either single or double quotes: More advanced strings can be created using escape sequences: String.prototype.format = function() { a = this; for (k in arguments) { a = a.replace("{" + k + "}", arguments[k]) } return a } All number methods can be used on any type of numbers (literals, variables, or expressions): Example.

Primitive values (like 3.14 or 2014), cannot have properties and methods (because they are not objects).

If you need to format currency for a different country / locale, you would need to add some modifications to the currencyFormat method.
