What is a Data Type?
A string is a sequence of characters, such as letters, numbers, and symbols. Strings are enclosed in quotation marks and can be used to store and manipulate text. For example, a string could be used to store a person’s name or a sentence.
A number is a data type used to store numerical values. Numbers can be integers (whole numbers) or floating-point numbers (numbers with decimal points). Numbers can be used to perform mathematical operations, such as addition, subtraction, multiplication, and division.
Bigint is a data type used to store large integers. Bigint is a newer data type and is not supported in all browsers. Bigint is useful for applications that require large integers, such as cryptography.
A Boolean is a data type used to store true or false values. Booleans are often used in control flow statements, such as if/else statements, to determine whether a certain condition is true or false.
Undefined is a data type used to indicate that a variable has not been assigned a value. Variables that have not been assigned a value will return undefined when accessed.
Null is a data type used to indicate that a variable has been assigned a value of null. Null is often used to indicate that a variable has no value.
A symbol is a data type used to create unique identifiers. Symbols are useful for creating unique identifiers, such as object properties.
An object is a data type used to store collections of data. Objects are composed of key-value pairs and can be used to store complex data structures.
