I have an array with strings:
const fruits = ['Apple', 'Banana', 'Orange']
I am trying to write a function that returns true or false depending on if a string starts with any string in the array, which would be true for example
some(), and combining them is sort of what I am after.
How would I do this?
some on the array and return the result of
theString.startsWith(theArrayEntryForEachLoopIteration), like this:
const theString = "Applepie"; const result = fruits.some(fruit => theString.startsWith(fruit));
result will be
true if there was a match (your callback returned a truthy value),
false if there wasn’t (your callback never returned a truthy value).
some will also stop looking the first time your callback returns a truthy value, since there’s no point in looking further.
const fruits = ['Apple', 'Banana', 'Orange']; // Example where it's there: const theString = "Applepie"; const result = fruits.some(fruit => theString.startsWith(fruit)); console.log(result); // Example where it isn't const theString2 = "Toffeepie"; const result2 = fruits.some(fruit => theString2.startsWith(fruit)); console.log(result2);
