Sometimes, we want to instantiate, initialize and populate an array in TypeScript.
In this article, we’ll look at how to instantiate, initialize and populate an array in TypeScript.
How to instantiate, initialize and populate an array in TypeScript?
To instantiate, initialize and populate an array in TypeScript, we can make a new class.
For instance, we write
class Bar {
constructor(public length: number) {}
}
const bars = [new Bar(1)];
to define the Bar
class that takes the length
parameter in the constructor
.
And it’ll assign the length
value to the length
instance property.
Then we define the bars
array and assign it an array that has a Bar
instance.
