In this session today we will learn to implement variable and array in java script.

  • To implement arrays and variables in java script follow the steps given below :

  1. Create an new folder on desktop.
  2. Inside that folder create an file index.html
  3. Now right click on file index.html and select an option edit with notepad++.
  4. v0

  5. After it gets opened in Notepad++ write the following code in it.

  6. The notepad++ window will look like as shown below :
  7. v1

  8. And the output of the window is shown below:
  9. v2

  10. Now write the following code in an Notepad++ window.

  11. Your window will have the following look :
  12. v3

  13. The output of the following window is as follows :
  14. v4

  15. We can also concatenate the string ,so for concatenating the string write the code given below in single quote.

  16. Your coded Notepad++ window will look like as shown below :
  17. v5

  18. So you will have the following output window:
  19. v6

  20. Let’s take another example for declaring a variable,so write the following code in Notepad++ window.

  21. So after writing the code your Notepad++ window will look like as shown below :
  22. v7

  23. After running it on browser you will have following Output :
  24. v8

  25. Now let’s learn to display the array element,so for displaying it write the following code in Notepad++.

  26. Your coded window will have following look :
  27. v9

  28. You will have following output :
  29. v10

  30. We can also add an next element in an array and access it by calling its index value,so to do it lets write the following code :

  31. The Notepad++ window will look like this:
  32. v11

  33. You will have the following output :
  34. v12

  35. We can also declare an array using square bracket.

  36. v13

  37. You will have following output :
  38. v14

  39. An array is an object and Object has the properties,so to understand it write the following code :

  40. Your coded window will have the following look :
  41. v15

  42. You will have the following output :
  43. v16

  44. Thus we have learnt to implement arrays and variables in Java Script.
