Function	Result	Notes
`IsEmailAddress("pooja.chatterjee@example.com")`	`true`

`IsEmailAddress("pooja.chatterjeeexample.com")`	`false`	This example is missing an at sign (@), making it invalid.
`IsEmailAddress("pooja@chatterjee@example.com")`	`false`	This example includes two at signs, making it invalid.
`IsEmailAddress("@example.com")`	`false`	This example is missing the local part (the part of the address that comes before the at sign), making it invalid.
