Answer 4

Case sensitive means taking the case type (uppercase and lowercase) into consideration when we do a string comparison.

For example, we have 4 string variables here.

// all lowercase
var stringA = "this is a text";

// mix of lowercase and uppercase
var stringB = "This is a Text";

// all uppercase
var stringC = "THIS IS A TEXT";

// all uppercase
var stringD = "THIS IS A TEXT";

print(stringA == stringB);
// false

print(stringB == stringC);
// false

print(stringC == stringD);
// true

Answer 5

When writing code a computer sees the value of a capital letter, A for example, as an ASCII value of 65, but to know whether an "A" or lower case "a" the lower case "a" has to be given a different ascii value. I believe it's 97. This is why case sensitive is important in needs to know which ascii value you require 65, or 97.
