What are the new data types in ES6 JavaScript?
The following are the different types of data types used in JavaScript.
- Numbers: Can represent both floating-point and integer numbers. Example: 5, 6.5, 7 etc.
- String: A sequence of characters is called a string. Strings can be enclosed in JavaScript within single or double quotes. Example: "Advanced JavaScript Questions" etc.
- Boolean: This represents a logical entity. It can have either true or false values.
- Null: This type only has one value: null
- Undefined: A variable whose value has yet to be assigned is undefined.
- Symbol: It is not a primitive data type that can be used to represent literal forms. It is a built-in object whose constructor returns a unique symbol.
- bigint: This is the bigint type that represents whole numbers larger than 253-1. You must add the letter n to the end of the number in order to form a literal bigint number.
- Object: This is the most crucial data-type. It forms the foundation for modern JavaScript. These data types will be discussed in more detail in future articles.
