CIS 119 Chapter 8

• Use the equality and identity operators.
• Use the relational operators
• Use the logical operators
• Use selection statements (if, switch)
• Use the conditional operator
• Use while and do/while loops
• Use for loops
• Use the break and continue statements

• Relational, logical, and bitwise operators
• if, if/else, switch, conditional operator
• for, while, do/while

• Relational operators
  • ==: equality (type coercion performed)
  • !=: inequality (type coercion performed)
  • ===: identity (type coercion not performed)
  • !==: non-identity? (type coercion not performed)
  • <: less than
  • <=: less than or equal to
  • >: greater than
  • >=: greater than or equal to
  • Operands converted to numbers except when both are strings
  • NaN is not equal to NaN
  • null is equal to undefined
  • false is equal to 0
  • true is equal to 1
  • the empty string is converted to 0 if numeric conversion is done
• Logical operators
  • !: not
  • &&: and
  • ||: or
• Operator precedence
  • !
  • <, <=, >, >=
  • ==, !=, ===, !==
  • &&
  • ||
• Selection
  • if
  • if/else
  • switch
  • break
  • conditional
• Repetition
  • while
  • do/while
  • for
  • for-in (iterates over enumerable properties)
  • for-of (iterates over itreable properties)
  • .forEach (applies function to each element in an Array object
  • break [label]
  • continue [label]
