JavaScript - convert character to ASCII code

In this article, we would like to show you how to convert characters to ASCII code in JavaScript. 

Quick solution:

// in case we want to convert a single character 
const charInASCII = 'your char'.charCodeAt(0);

Note: default argument of the charCodeAt() method is 0, so charCodeAt(0) can be replaced with charCodeAt().

Practical example:

In the example below, we convert characters to ASCII code at subsequent positions in the string.

// ONLINE-RUNNER:browser;
const exampleString = 'abc'
console.log(exampleString.charCodeAt(0));  // 97
console.log(exampleString.charCodeAt(1));  // 98
console.log(exampleString.charCodeAt(2));  // 99
