<h2>answer(source)</h2>
<ol>
<li>] Timers are used to execute a piece of code at a set time or also to repeat the code in a given interval of time. This is done by using the functions&nbsp;<strong>setTimeout, setInterval&nbsp;</strong>and<strong>&nbsp;clearInterval</strong>.</li>
<li>] The&nbsp;<strong>setTimeout(function, delay)</strong>&nbsp;function is used to start a timer that calls a particular function after the mentioned delay. The&nbsp;<strong>setInterval(function, delay)</strong>&nbsp;function is used to repeatedly execute the given function in the mentioned delay and only halts when cancelled. The&nbsp;<strong>clearInterval(id)</strong>&nbsp;function instructs the timer to stop.</li>
<li>] Timers are operated within a single thread, and thus events might queue up, waiting to be executed.</li>
</ol>
<h2>answer(me)</h2>
<ol>
<li>] js has a setTimeout method() which you can use to delay execution of code by a specified time value.&nbsp;</li>
<li>] js also has a setInterval method that you can use to continuously execute code at a specified interval, until you use clearInterval() to stop it</li>
<li>] One drawback is that&nbsp;this method&nbsp;is not asynchronious and&nbsp;blocks the execution of&nbsp;subsequent code when you use the setTimeout method.</li>
