I have an array named currentOrders.

if its length is 1 then I want to set the variable output to true if not false using javascript.

I writing something like this using ternary operator

const isOneOrder = currentOrders.length === 1 ? true : false;

You can completely remove the ternary operator:

let currentOrders = [1];
const isOneOrder = currentOrders.length === 1;
console.log(isOneOrder);
currentOrders = [1, 2];
const isNotOneOrder = currentOrders.length === 1;
console.log(isNotOneOrder);

you could write it like this

const isOneOrder = !!currentOrders.length;

when you add two !! it will convert the value to boolean

Simply you can write like this.

const isOneOrder = currentOrders.length === 1;

=== operator will return true if value and type are same and will return false in othercases.

Therefore, no need to define true or false.
