converting array of array into array js code example
Example 1: js convert array of arrays to array
// Converts array with multiple values into a single array with all items:
var merged = [].concat.apply([], arrays);
Example 2: flatten an array in javascript
// Although this now may be an older version of how to faltten an
// array of arrays. I still want to post it so some may have an understanding
// of how it works
function falltenArray(arr) {
let result = [...arr];
let flattened = false;
let counter = 0;
while (flattened === false){
// checks to see if the element at the counter index is an array
if (Array.isArray(result[counter])){
// unpacks the current array element back into the array
result.splice(counter, 1, ...result[counter]);
// if so the counter should start at the beginning of the array
counter = 0;
} else {
counter += 1;
}
if (counter === result.length){
flattened = true;
}
}
return result;
}
