What do you understand by bound and unbound expressions in the context of Salesforce Lightning?

Answer»
  • BOUND Expression: {!v.str} is the symbol for bound expression. This expression will reflect any changes in the STRING's value and will also influence the COMPONENTS where it is used, thus we can say the value changes dynamically through this expression.
  • UNBOUND Expression: {#v.str} is the symbol for unbound expression. This expression will not reflect any changes in the string's value; we can argue that the value REMAINS static as a result of this expression.
