Readme Needs a revamp

[ITSUREN]

Describe the bug

• The topic "Arithmetic Operators" is completely formatted wrong due to conflicts with default markdown formats
• The topic "Comperison Operators" is also formatted wrongly and also needs to be "Comparison Operators"
• Formatting on the topic "Comment in JS" is also wrong.
