javascript loop through array
var data = [1, 2, 3, 4, 5, 6];
// traditional for loop
for(let i=0; i<=data.length; i++) {
console.log(data[i]) // 1 2 3 4 5 6
}
// using for...of
for(let i of data) {
console.log(i) // 1 2 3 4 5 6
}
// using for...in
for(let i in data) {
console.log(i) // Prints indices for array elements
console.log(data[i]) // 1 2 3 4 5 6
}
// using forEach
data.forEach((i) => {
console.log(i) // 1 2 3 4 5 6
})
// NOTE -> forEach method is about 95% slower than the traditional for loop
// using map
data.map((i) => {
console.log(i) // 1 2 3 4 5 6
})
