I would like to represent you some useful Javascript helper functions for manipulating data.

.forEach()

forEach() calls a provided callback function once for each element in an array in ascending order.

Syntax:

arr.forEach(callback(currentValue[, index[, array]]) {

Example:

forEach() function

.filter()

let newArray = arr.filter(callback(currentValue[, index[, array]]) {
// return element for newArray, if true
}[, thisArg]);

Time() & TimeEnd()

Error()

Outputs an error message to the console.
