Comparison

Greater than or equal to (>=)

console.log(5 >= 3); // true
console.log(3 >= 3); // true

// Compare bigint to number does not work
console.log(3n >= 5); // false

console.log("ab" >= "aa"); // true
"a" >= "b"; // false
"a" >= "a"; // true

Less than or equal to (<=)

console.log(5 <= 3); // false

console.log(3 <= 3); // true

// Compare bigint to number does not work
console.log(3n <= 5); // true

console.log("aa" <= "ab"); // true
"a" <= "b"; // true
"a" <= "a"; // true

Comparing whether more than 3 elements are equal to each other?

Comparison logic for up to three elements is straightforward. Comparing more elements need more clever solutions.

/* manual comparison of 3 elements */ 
if(g === h && g === f) { "do something" } 

/* looping comparison of n-elements */ 
function nEqual(){
  for (let i = 1; i < arguments.length; i++){
    if (
        arguments[i] === null || 
        arguments[i] !== arguments[i-1]
      ) {
        return false;
      }
  return true;
};

nEqual(a,b,c,d,e,f,g,h) && { "do something" }
