ZIM Review

Here is a chart of examples showing ZIM at 37% less code the developer writes when compared to other frameworks such as PixiJS, Flutter, CreateJS, PaperJS, P5js, Phaser and the DOM.

It is quite common in ZIM to not even store an object in a variable as chaining is available for almost all methods and there are short chainable methods for most properties.
new Circle().center().drag();
new Rectangle()
.loc(100,100)
.alp(0) // alpha
.animate({x:200, alpha:1}, .5);

new Tile(new Circle(20, series(red, blue, green), 10, 10).center();
// tiles 10x10 circles with colors is series of red, blue or green
new Emitter([new Circle(), new Rectangle()]).center();
// emits random circles and rectangles
interval({min:1, max:3}, ()=>{});
// each interval is between 1 and 3 seconds

So passing in a series lets you pick in order, passing in an array lets you pick randomly, passing in a min/max range picks from the range, passing in a function picks the result of the function. These can be applied to all styles too.

Style = {
color:red,
Button:{
color:blue;
}
}
new Circle().center(); // red
new Button().center(); // blue

For instance:
new Rectangle(100,100,undefined,undefined,undefined,20).center();
or
new Rectangle({width:100, height:100, corner:20}).center();
