for loop on a array
var array = [1, 2, 3, 4, 5];
// made an array
for (var i = 0; array[i]; i++) // browse your array with this simple condition on index
console.log('element '+i+' = '+array[i]);
//output:
element 0 = 1
element 1 = 2
element 2 = 3
element 3 = 4
element 4 = 5loop an array in javascript
let array = ["loop", "this", "array"]; // input array variable
for (let i = 0; i < array.length; i++) { // iteration over input
console.log(array[i]); // logs the elements from the current input
}arrays with for loops
// Given an array of booleans representing a series
// of coin tosses (true=heads, false=tails),
// returns true if the array contains anywhere within it
// a string of 10 heads in a row.
// (example of a search loop)
public boolean searchHeads(boolean[] heads) {
int streak = 0; // count the streak of heads in a row
for (int i=0; i<heads.length; i++) {
if (heads[i]) { // heads : increment streak
streak++;
if (streak == 10) {
return true; // found it!
}
}
else { // tails : streak is broken
streak = 0;
}
}
// If we get here, there was no streak of 10
return false;
