// let x = 10

//shortcut
//x = x + 1 x = x / 2 / x++ x--
// x /= 2
// x %= 2

//operands++
//+ operands

// console.log(--x)
// console.log(x)

// console.log(++x)
// console.log(x)

//comparison
console.log(1 == Number('1')) //only consider value
console.log(1 === '1') //consider both value and type

//conversion (explicit)
//coercion(implicit conversion)

// concatenation (+)

//if any of the part  is string , convert other part to string
// console.log(1 + 'Hello')
// //else(- * / %) javascript try it's to calculate the result
// //if possible you will get number
// console.log('10' * true)
// //or not Possible -NaN
// console.log(1 * 'Hello') //NaN

//operator precedence and associativity
// console.log(2 * (2 * 3))

//object({}, [], null)
//Array
// console.log(Array.isArray({}))
// //compare null === null , undefined == null

// //number(10, NaN)
// console.log(Number.isNaN(Number('ggjgb')))

//undefined vs null
// let z;
// console.log(z)

// let bogus = null
// console.log(bogus === null )
