Will Typescript support destructuring assignments similar to CoffeeScript?
foo = {x: 1, y: 2, z: 3}
{x, z} = foo
# which will yield
x == 1 && z == 3

Tuples in TypeScript are basically a simple Array with definite length and definite Data-type. Destructuring means breaking the structure. In this article we will see how Destructuring of tuple in TypeScript work. Destructuring is simply breaking up into part and assigning to variables.
The destructuring is also possible for JavaScript Arrays. By default, the object key name becomes the variable that holds the respective value. So no extra code is required to create another variable for value assignment.
Destructuring in Objects When destructuring objects, we use curly braces with the exact name of what we have in the object. Unlike in arrays where we can use any variable name to unpack the element, objects allow just the use of the name of the stored data.
A nifty use for value destructuring is unpacking string characters. Which comes in handy when doing typical string ops like slugify .
Yes, it will.
