Used an alternative to if..else if statements
Evaluates an expression, and matches that expression against each of the case clauses
if there’s a match, the statements associated with that case clause will be executed
The break keyword must be used to exit the Switch statement after a match is found
switch(expression) {
case x:
// execute code block when expression === x
break // <- break must be called to exit the switch statement after the match
case y:
// execute code block when expression === y
break // <- break must be called to exit the switch statement after the match
default:
// execute code block when expression === when none of the above cases match
}
const food = "apple"
switch(food) {
case 'pear':
console.log("I like pears")
break
case 'apple':
case 'oranges':
console.log("I like apples & oranges")
break
case 'grapes':
console.log("I like grapes")
break
default:
console.log("Your fruit selection is weak :(")
}
Rewrite the following if..else if statement using a switch statement:
const yourGrade = "C"
if (yourGrade === "A") {
console.log("You earned an A!")
} else if (yourGrade === "B") {
console.log("You earned a B")
} else if (yourGrade === "C") {
console.log("You earned a C")
} else {
console.log("You earned less than a C")
}
