Lets say we need to make a function doSomething
. we need to do it in a way so that it can handle both arguments: (1) a string and (2) an array of strings.
To achieve that previously I used to do something like this:
function doSomething(strs) {
function _doSomething(str) {
// some mysterious stuff happening here
console.log(str)
}
if (Array.isArray(strs)) {
return strs.map(str => _doSomething(str))
} else {
return _doSomething(strs)
}
}
doSomething(["hello", "world"])
doSomething("hello")
now since I learned recursion I do this:
function doSomething(strs) {
if (Array.isArray(strs)) {
return strs.map(str => doSomething(str))
} else {
console.log(strs);
}
}
doSomething(["hello", "world"])
doSomething("hello")

but typescript don`t like it.
Typescript doesnt know anything 😑
