so lets say I created an array that is ..
let foods = ['oranges', 'pears', 'peaches]
now I want to create a function that allows me to select any of the elements and convert it to uppercase letters how would I go about doing that?
In javascript you could do something like:
let foods = ["oranges", "pears", "peaches"];
function uppercase(array, index) {
for (i = 0; i < array.length; i++) {
if (i == index) {
console.log(array[i]);
result = array[i].toUpperCase();
return result;
}
}
}
result = uppercase(foods, 1);
console.log(result);
I hope this can help you:
example 1: convert to uppercase using index of element
let foods = ['oranges', 'pears', 'peaches']
const convertToUppercase = (index) => {
return foods[index].toUpperCase()
}
console.log(convertToUppercase(0))
example 2: convert to uppercase by element (text you want to convert)
let foods = ["oranges", "pears", "peaches"];
const convertToUppercase = (element) => {
return element.toUpperCase();
};
foods.forEach((element) => {
console.log(convertToUppercase(element));
});
example 3: convert the entire array to uppercase
let foods = ["oranges", "pears", "peaches"];
const convertToUppercase = (array) => {
let converted =[]
array.map((element) =>
converted.push((element.toUpperCase()))
);
return converted;
};
console.log(convertToUppercase(foods));
This will help, thanks
const foods = ['oranges', 'pears', 'peaches']
const toUpper = s => s.toUpperCase()
console.log(foods.map(toUpper))
