MDN has a good overview of how bitwise operators work. There is no easy way to create a bit-string representation of this in javascript nor access specific bits. The internal representation of numbers is 64 bit floating point and some limitations are discussed in this answer. In this system negative numbers are written with minus signs just like in decimal. (123456).toString(2) will convert numbers to the base 2 positional numeral system. (for 64bit bitstrings see Patrick Roberts' answer) The positional number system, the binary representation in memory or 32bit bitstrings. Please show your love and support by sharing this post.The binary in 'convert to binary' can refer to three main things. Perhaps, depending on your needs, you could instead consider using the String() wrapper object or the toString() method. Using the template literal syntax solely for the purpose of converting integers to strings might not be the best idea as it does not make the intention immediately clear. Introduced in ES6, you may use the template literal (template string) syntax to convert a number to a string: Perhaps, depending on your needs, you should instead consider using the String() wrapper object or the toString() method. This is because it makes the code not very readable and the intention (of integer to string conversion) is not immediately clear. In practice you should avoid using this method if you're using string concatenation solely for converting an integer to a string. The empty string can be placed before or after the number the order of it does not matter: This means that you can use an empty string in a concatenation to convert an integer to a string:Ĭonsole.log(typeof numericStr) // 'string' When a number literal is used in a string concatenation, the number value is automatically coerced into a string:Ĭonst str = 'Hi, I am ' + 21 + ' years old' This is because NaN itself is of type number: Instead NaN is converted to a string as is: However, same is not true if the variable holds the value NaN. TypeError: Cannot read properties of null (reading 'toString') TypeError: Cannot read properties of undefined (reading 'toString') If the integer you wish to convert to string is in a variable, and that variable can potentially be undefined or null, then please be aware that calling toString() will throw an error: Number(12345)), which allows it to access the property/method on that object (e.g. The reason why toString() method works on a primitive (such as a number) is because when properties/methods (such as ()) are accessed on primitives, JavaScript auto-boxes the value into a wrapper object (i.e. Uncaught Synta圎rror: Invalid or unexpected tokenįor toString() to work with numbers, you can do any the following: You can't directly call the toString() method on a number literal: If the variable holding the integer can potentially be null, undefined, etc., then please be aware that those would be converted to strings as is: This would result in a new String primitive. You can convert an integer to a string by using the String wrapper object, for example, like so: You can convert an integer to a string in JavaScript, in the following ways:
