Return value = null ? '' : (typeof value = 'object' & !value. How to Use the toString Method in JavaScript To use the toString () method, you simply need to call the method on a number value. If you don't like strings like 'Hello, undefined' or want to support prototype-less objects, use the following type conversion function: /** The toString () method is a built-in method of the JavaScript Number object that allows you to convert any number type value into its string type representation. Note: String(x) will still fail on prototype-less objects like Object.create(null). Syntax: num. It is used to return a string representing the specified Number object. This function parses the string argument as a signed decimal integer. JavaScript Number toString () method in Javascript is used with a number and converts the number to a string. X.toString() throws on nulls and undefined. Method 1: Use Integer.parseInt () method This is the most simple method to convert String to integer. valueOf() on x (casting to number), throws on Symbols, can provide implementation dependent results. String(x) handles nulls, undefined, Symbols, and calls. To convert an integer to its equivalent character in JavaScript, apply the combined charCodeAt() and omCharCode() methods. Return value A floating point number parsed from the given string, or NaN when the first non-whitespace character cannot be converted to a number. Leading whitespace in this argument is ignored. Do not use 3 ways for simple operation, basing on value type assumptions, like "here I convert definitely number to string and here definitely boolean to string". In JavaScript, users use the parseInt() to give input as strings and radix parameters and convert that input into an integer. Syntax parseFloat(string) Parameters string The value to parse, coerced to a string. The only valid solution for almost all possible existing and future cases (input is number, null, undefined, Symbol, anything else) is String(x).
