The typeof operator in JavaScript is a unary operator that is used to return a string indicating the type of the operand's value. It is particularly useful in a dynamically typed language like JavaScript, where the type of a variable can change at runtime. The operand can be any object, function, or variable, and the typeof operator evaluates the type of the operand and returns the result as a string[1][2][4][5][6][7].
JavaScript has several data types, and the typeof operator can help you determine if a value is a number, string, boolean, object, function, undefined, symbol, or bigint. For example, using typeof on a number would return the string "number", and using it on a string would return "string"[1][2][4][5][6][7].
However, there are some nuances and caveats to be aware of when using typeof. For instance, null is an object in JavaScript due to a historical bug, so typeof null will return "object" instead of "null". Similarly, arrays and functions are also considere...
