Write Small Functions

• Keep your functions short or Avoid large functions. A good function fits on a slide that the people in the last row of a big room can comfortable read.

• Avoid Deep nesting

  const myArray = [ [ [ 'value' ] ] ];
  // Doconst retrieveValue = (element) => {  if(Array.isArray(element)) {    return retrieveValue(element[0]);  }  return element;}retrieveValue(myArray);
  // AvoidmyArray.forEach((array1) => {  array1.forEach((array2) => {    array2.forEach((element) => {      console.log(element);    })  })});
