A controlled component is bound to a value and its changes get handled in code using event based callbacks. class CustomForm extends React.Component { constructor() { super(); this.state = { person: { firstName: '', lastName: '' } } } ...

z1 = zeros(5); % Create a 5-by-5 matrix of zeroes z2 = zeros(2,3); % Create a 2-by-3 matrix

o1 = ones(5); % Create a 5-by-5 matrix of ones o2 = ones(1,3); % Create a 1-by-3 matrix / vector of size 3

i1 = eye(3); % Create a 3-by-3 identity matrix i2 = eye(5,6); % Create a 5-by-6 identity matrix

<ul> <li *ngFor="let item of items">{{item.name}}</li> </ul>

<div *ngFor="let item of items"> <p>{{item.name}}</p> <p>{{item.price}}</p> <p>{{item.description}}</p> </div>

<div *ngFor="let item of items; let i = index"> <p>Item number: {{i}}</p> </div> In this case, i will take the value of index, which is the current loop iteration.

Angular2 provides several exported values that can be aliased to local variables. These are: index first last even odd Except index, the other ones take a Boolean value. As the previous example using index, it can be used any of these exported values: <div *ngFor="let item of item...

A thread-local object gets initialized on its first use in a thread. And as the name suggests, each thread will get a fresh copy independent of other threads. use std::cell::RefCell; use std::thread; thread_local! { static FOO: RefCell<f32> = RefCell::new(1.0); } // When this mac...

Sometimes we don't want to load the entire XML file in order to get the information we need. In these instances, being able to incrementally load the relevant sections and then delete them when we are finished is useful. With the iterparse function you can edit the element tree that is stored while ...
