For...of Loops
๐จโ๐ผ When you want to iterate over an array and just need each value (not the
index),
for...of provides clean, readable syntax.The syntax:
for (const item of array) {
// use item
}
For example:
const fruits = ['apple', 'banana', 'cherry']
for (const fruit of fruits) {
console.log(fruit)
}
// Logs: apple, banana, cherry
