Shorthand if/else statement Javascript

Question

I\'m wondering if there\'s a shorter way to write this:

var x = 1;
if(y != undefined) x = y;

I initially tried x = y || 1, but

Answer 1

You can try if/else this shorthand method:

// Syntax
if condition || else condition

// Example
let oldStr = "";
let newStr = oldStr || "Updated Value";
console.log(newStr); // Updated Value

// Example 2
let num1 = 2;
let num2 = num1 || 3;
console.log(num2);  // 2  cause num1 is a truthy
