Every time a new value is added to such a generic array, the compiler checks for type compatibility and alerts if there is a type mismatch. To use the type-safety capability of TypeScript, we can add diamond brackets to specify the type of elements in the array. The array is specified by adding a square bracket after the type. Like JavaScript, TypeScript has an Array type to allow the assignment of multiple values. In this tutorial, we will learn to create an array, clone an array, merge arrays and iterate through the elements of an array in TypeScript with easy-to-follow examples. Individual elements at various positions in the array are accessed via their index. An array, once it is created, cannot be resized. A typescript array can store multiple values of the same data types sequentially.Īrrays are always of fixed size. Arrays in typescript are of fixed-length and homogeneous collection of values very similar to other programming languages.
