JavaScript New Keyword
Description
When you put the keyword new
in front of a function call, the function
is treated as a constructor. An object
with the proper prototype
is automatically created, bound to this
in the function and returned
at the end of the function. This allows you to do OO type stuff.
Syntax
function Rabbit(type) {
this.type = type
}
Rabbit.prototype.speak = function (line) {
console.log(`The ${this.type} rabbit says '${line}'`)
}
let weirdRabbit = new Rabbit("weird")
weirdRabbit.speak("I want carrots!")
