The basic data types of JS are as follows: Number, String, Boolean, Null, and Undefined.
let num1 = 10; // 整数 let num2 = 3.14; // 浮点数
let str1 = 'Hello'; // 使用单引号 let str2 = "World"; // 使用双引号
let isTrue = true; // 真 let isFalse = false; // 假
let emptyValue = null;
let undefinedValue;
The above are the basic data types of JS and their corresponding code examples. In actual development, we often use these data types to store and operate different data.
