TypeScript letflag:boolean;letyes =true;letno =false; Number and BigInteger types As in JavaScript, all numbers in TypeScript are either floating point values or BigIntegers. These floating-point numbers get the typenumber, while BigIntegers get the typebigint. In addition to hexadecimal and ...

A primitive type has a fixed size in memory. For example, a number occupies eight bytes of memory, and a boolean value can be represented with only one bit. The number type is the largest of the primitive types. If each JavaScript variable reserves eight bytes of memory, the variable can...
Returns the type of the value represented by the current CSSPrimitiveValue object. Depending on the type, the appropriate getter method needs to be used to retrieve the represented value. See the examples for details.

Boolean is a data type in JavaScript. Boolean can have only two values, true or false. It is useful in controlling program flow using conditional statements.
