How to Concatenate Strings in Array in TypeScript ?

Answer

To concatenate strings in an array in TypeScript, you can use the `join` method or a loop to iterate through the array and concatenate each element.

✐ Examples

1 Concatenate Strings in Array with join()

In this example,

We create an array `words` with strings.
We use the `join` method with the array to concatenate strings.
We print the concatenated string.

TypeScript Program

const words: string[] = ["Hello", "World", "!"];
const concatenated: string = words.join(" ");
console.log(`Concatenated String: ${concatenated}`);

Output

Concatenated String: Hello World !

2 Concatenate Strings in Array with Loop

In this example,

We create an array `words` with strings.
We initialize an empty string `concatenated`.
We use a for loop to iterate through the array and concatenate each element to `concatenated`.
We print the concatenated string.

TypeScript Program

const words: string[] = ["Hello", "World", "!"];
let concatenated: string = "";
for (const word of words) {
    concatenated += word + " ";
}
console.log(`Concatenated String: ${concatenated.trim()}`);

Output

Concatenated String: Hello World !
