The for statement creates a loop that consists of three optional expressions, enclosed in parentheses and separated by semicolons, followed by a statement (usually a block statement) to be executed in the loop. A loop usually has one or more of the following features: A counter, which is initialized with a certain value — this is the starting point of the loop ("Start: I have no food", above). A condition, which is a true/false test to determine whether the loop continues to run, or stops — usually when the counter reaches a certain value. This is illustrated by "Have I got enough food?" above. Let's say he needs 10 portions of food to feed his family. An iterator, which generally increments the counter by a small amount on each successive loop until the condition is no longer true. We haven't explicitly illustrated this above, but we could think about the farmer being able to collect say 2 portions of food per hour. After each hour, the amount of food he has collected is incremented by two, and he checks whether he has enough food. If he has reached 10 portions (the point where the condition is no longer true, so the loop exits), he can stop collecting and go home.<pre class="ql-syntax ql-indent-1" spellcheck="false">loop(food = 0; foodNeeded = 10) {
 if (food &gt;= foodNeeded) {
 exit loop;
 } else { // this is example!!
 food += 2;
}
</pre>&lt;h1&gt;test html&lt;/h1&gt;So the amount of food needed is set at 10, and the amount the farmer currently has is set at 0. In each iteration of the loop, we check whether the amount of food the farmer has is larger or equal to the amount he needs. If so, we can exit the loop. If not, the farmer spends an hour collecting two portions of food and the loop runs again.
