Description : Implementing `@while` loops for repetitive tasks in SASS.
Answer :
`@while` loops inSASS are used for executing code repeatedly while a condition is true. For example, generate a series of classes with incremental values using `@for $i from 1 through 5 { .col-#{$i} { width: #{20 * $i}px; } }`. This loop creates `.col-1`,`.col-2`, etc.,with widths increasing by 20px, simplifying the creation of repetitive styles.
