Javascript ?? vs ||

Found this great article → https://www.trevorlasn.com/blog/javascript-logical-operators

This is a small and useful snippet that makes it very clear on when to use ?? and when to use ||

// Let's see what || considers "falsy":
0 || "default"         // returns "default"
"" || "default"        // returns "default"
false || "default"     // returns "default"
null || "default"      // returns "default"
undefined || "default" // returns "default"

// Now compare with ??:
0 ?? "default"         // returns 0 ✨
"" ?? "default"        // returns "" ✨
false ?? "default"     // returns false ✨
null ?? "default"      // returns "default"
undefined ?? "default" // returns "default"
