Expert Developer JavaScript Question:
Explain the for-in loop?
Answer:
The for-in loop is used to loop through the properties of an object.
The syntax for the for-in loop is -
for (variable name in object){
statement or block to execute
}
In each repetition, one property from the object is associated to the variable name, and the loop is continued till all the properties of the object are depleted.
