Question and Answer Section
Q: What is the difference between the Map function and the ForEach function?
A: While both functions allow you to iterate through an array, the Map function creates a new array with the results of calling the specified function on each element, while the ForEach function simply executes the specified function on each element without returning a new array.
Q: Can the Map function be used with nested arrays?
A: Yes, the Map function can be used with nested arrays. You can simply apply the function to the outer array and use another function to iterate through the nested arrays.
Q: What is the syntax for using the Map function in Javascript?
A: The syntax for using the Map function in Javascript is as follows: array.map(function(currentValue, index, arr), thisValue)
Q: Is the Map function supported in all modern web browsers?
A: Yes, the Map function is supported in all modern web browsers, including Chrome, Firefox, Safari, and Edge.
