Pretty simple – I’m trying to include a utility class in a React application that isn’t a React class component, but I keep getting the error: Class constructor Stack cannot be invoked without 'new'

Here’s the class:

export default class Stack<T>  {

    private stack: T[] = []

    // Push an item onto the stack
    push(item: T): void {
        this.stack.push(item)
    }

    // Pop the top item from the stack and return it
    pop(): T | undefined {
        return this.stack.pop()
    }

    // Check if the stack is empty
    isEmpty(): boolean {
        return this.stack.length === 0
    }

    // Get the current size of the stack
    size(): number {
        return this.stack.length
    }

    // Peek at the top item of the stack without removing it
    peek(): T | undefined {
        return this.stack[this.stack.length - 1]
    }
}

Any hints/tips how I can include this via import like a normal class?

Cheers,

Tried to compile as per normal and can’t include/instantiate the class. I’m also using typescript, so it may have something to do with my tconfig.json, but hard to tell what exactly without more information/help.
