Sample text
Js Platform In this case, we are writing a module that exports the functions square and cube mapped to properties with the same name. Notice that we don't need to specify the keyword function. Let's see in another example how we can use computed property names: const namespace = '-webkit-'; const style = { [namespace + 'box-sizing'] : 'border-box', [namespace + 'box-shadow'] : '10px10px5px #888888' }; In this case, the resulting object will contain the properties -webkit-box-sizing and webkit-box-shadow.
Return true; } }); But there is another important feature to know about arrow functions: arrow functions are bound to their lexical scope. This means that inside an arrow function the value of this is the same as in the parent block. greet(); // will print "Hello undefined" In this code, we are defining a simple greeter prototype that accepts a name as an argument. Then we are adding the greet method to the prototype. This function is supposed to print Hello and the name defined in the current instance 500 milliseconds after it has been called.
Org/en-US/docs/Web/Ja vaScript/Guide/Closures. In this section, we will analyze this particular style of programming that's made of callbacks instead of x return instructions. The continuation-passing style In JavaScript, a callback is a function that is passed as an argument to another function and is invoked with the result when the operation completes. In functional programming, this way of propagating the result is called continuation-passing style (CPS). It is a general concept, and it is not always associated with asynchronous operations.
