Use forEach Loop:

The forEach() method executes a provided function once for each array element

const someArray = [1,2,3,4,5,6,6];
someArray.forEach((value) => {
    console.log(value);
});

with elment index:

const someArray = [1,2,3,4,5,6,6];
someArray.forEach((value,index) => {
   console.log(value,index);
});

Use for loop:

for loop operates on the values sourced from an iterable one by one in sequential order.

const someArray = [1,2,3,4,5,6,6];
for (let index = 0; index < someArray.length; ++index) {
    const element = someArray[index];
    console.log(element,index);
}
