Data Types in ECMA Script

JavaScript is a dynamic language with dynamic types. Variables in JavaScript are not directly associated with any particular value type, and any variable can be assigned (and re-assigned) values of all types. JavaScript is also a weakly typed language, which means it allows implicit type conversion when an operation involves mismatched types, instead of throwing type errors. 0:20 Data types 2:51 Primitive values 3:03 Boolean type 3:09 Number type 3:43 BigInt type 5:05 String type Symbol type A Symbol is a unique and immutable primitive value and may be used as the key of an Object property
