Statement and Expression

let x = 5 + 3  // whole line is statement

// 5+3  <-- expression

Expression​

  • it will turn out to be a single value
let x = 6 + 4
let y = x + 2
let z = (y + 4) * 3  
let a = z

What is​

  • Statement = whole line
  • Expression = what is present in right side of the equal '='
  • Expression can be evaluated as a single value
  • Single variable/value is also an expression

Remember the if() syntax​

if (expression) {
  statement;
} else if (expression) {
  statement;
} else {
  statement;
}
