Q7: == vs === the answer does't mention the loose equality coercion

[mooSylla]

In js when we loosely compare 2 different types the loose equality operator coerces those types to numbers before performing the comparison.

1 == true ==> 1 == 1 ==> true
1 == [1] ==> 1 == "1" ==> true
1 == [2] ==> 1 == "2" ==> false
0 == false ==> 0 == 0 ==> true

ps : Special case for null and undefined
null == undefined ==> true

The current answer for Q7 can be improved by explicitly mentioning type coercion:

• == (loose equality) coerces types before comparing
• === (strict equality) compares type + value, no coercion

Examples:

• 1 == "1" → true (string coerced to number)
• 0 == false → true
• null == undefined → true (special case)
• null === undefined → false
