Map Function In JavaScript
Map Function In JavaScript:
Map Function Calls a Callback Function For Each element In a Array And Constructs a new Array. The Below Example explains the map function clearly At first array is declared we need to solve the Array for different solutions but the array value is same . To get different solutions for same array we use map functions that we map the functions to array according to the problem. Here I have taken four examples
Example 1:
I have made a function to the logic to double the number and i have given function name and given the return value multiplied by 2 and console.log the output gives the exact expected output.
Example 2:
I have made a function to make the array give the cube of the value . I have written a function that returns the cube with the logic multiplying it three times.
Example 3:
I have made a function to make the values give the hexadecimal value of the array . I have written a function with To string which converts the Array to the hexadecimal
Example 4:
In this Function I have used a Higher order function to map the Value And there is also another method as arrow Function to map the array and in this function I have used the square to get the square of the array
the Map function is used to give many function to a single value by mapping the function to the value
for eg: there is a car and car has many functions to do like Moving , Horn and Acceleration All this functions are mapped to the car.
