Could you please format your code properly? There seem to be typos and missing characters in them too.

To format code blocks, markdown requires surrounding the code with lines consisting of triple backquote.

Code Formatting

This forum supports Github Flavored Markdown Standard Markdown converts text with four spaces at the beginning of each line into a code block; GFM also supports fenced blocks. Just wrap your code in ``` (as shown below) and you won’t need to indent it by four spaces. For example: ```js console.log('hello world'); ``` will output: console.log('hello world'); Other choices for language include C#, Visual Basic, JSON and XML.
