Equality and Relational Operators
For the statement to return false, you can simply use the "not equal to" equality operation. The full symbol of this operation is '!=', disregarding the quotes.
<u>Examples:</u>
- [1 != 1] would produce FALSE. Translation: 1 <u>does not equal</u> 1?
- [1 == 1] would produce TRUE. Translation: 1 <u>does</u> 1?
- ["G" != "G] would produce <u>FALSE</u>. Translation: "G" <u>does not equal</u> "G"?
CONCLUSION: Use "!=".
