Teacher asks:
/**
* Challenge: write the code to check if the parameter is a string
* or a number, and use the menu.find() method accordingly
*/
I cant use “identifier string | number” inside the if statement because it doesnt work.
I also dont understand what he wants me to do exactly. Am I just dumb? Teacher isnt explaining what he wants us to do…
function getPizzaDetail(identifier: string | number) {
/**
* Challenge: write the code to check if the parameter is a string
* or a number, and use the menu.find() method accordingly
*/
if (identifier string | number) {
}
}
The following is what he wants us to write:
function getPizzaDetail(identifier: string | number) {
if (typeof identifier === "string") {
return menu.find(pizza => pizza.name.toLowerCase() === identifier.toLowerCase())
} else {
return menu.find(pizza => pizza.id === identifier)
}
}
I didnt know to use “type of”, i didnt know if that i shouldve written something about “pizza”, “tolowercase” to use === with it, also he told us to only write the if statement, not else…
