Using lambdas and LINQ in C#, I can create a new collection with a certain type based on a collection with a different type. For instance:
var array = new List<Foo> { new Foo { name = "John", age = "21", title = "Mr." } };
// I can then use the Select function to create a collection with a different type
var modifiedArray = array.Select(foo => new Bar { title = foo.Title });
I was wondering if there is a better way to do this in Javascript. I currently have:
var array = [{name: 'John', age: '21', title: 'Mr.'}];
var modifiedArray = [];
array.forEach(function(foo){
modifiedArray.push({title: foo.title});
});
Yes. You can use Array.prototype.map
var modifiedArray = array.map(function(x){
return {title: x.title}
});
