TypeCoercion.js

/* Type coercion is the process of converting one type of value into another. There are 3 
types of conversion in JavaScript.
• to stringx
• to boolean
• to number
*/

let num = 1;
let str = "1";
num == str; // true
// notice loose equality ==, not ===
// double equals (==) will perform a type conversion
// one or both sides may undergo conversions
// in this case 1 == 1 or '1' == '1' before checking equality

/* Strict equals: The triple equals (===) or strict equality compares two values 
without type coercion. If the values are not the same type, then the values 
are not equal. This is almost always the right way to check for equality in 
JavaScript, so you don't accidentally coerce a value and end up with a bug in 
your program. Here is the MDN Equality Comparison page and 
the ECMAScript Comparison Algorithm */
