<pre class="shiki github-dark shaku"><code>function foo(){ console.log(1) }var foo = 2function foo(){ console.log(3) }foo()</code></pre>
Solution: <code>Error</code>
Reason:
Line 1: Hoisting will take place, Function declaration will be hoisted and in the global object foo will be equal to a function.
Line 2: foo variable will be hoisted. Now since foo keyword is already present in the global object as a function it will get replaced by foo variable (foo=2).
Why did this happen?
Because variable assignment has more importance than function declaration (when the name of variable and function are the same)
Order of Precedence: variable Assigment &gt; function declaration &gt; variable declaration
Line 3: It will have no effect due to the above-mentioned rule.
Line 4: Since foo is not a function it will throw an error.
