JavaScript as a Dynamic (loosely typed) language:

  • dynamic/loosely typed means you don't have to specify what type of information will be stored in a variable beforehand
  • the variable type is determined while the code is running, which is similar to Python
//string:
console.log("hello")
//number:
console.log(22)
//generic object: array (similar to python list)
console.log([1,2,3])

hello
22
[ 1, 2, 3 ]
