Javascript does not equal shorthand update#

Update 1: Due to a lot of polarizing comments (like loved or hated the article) I just want to be clear that shorthand are useful sometimes and sometimes. However, the or Strict inequality operator does not attempt to do so and returns false if the values are unequal or of. This operator tries to compare values irrespective of whether they are of different types.

Using the if/else statement, we check if the age is greater than or equal to 18, and assign the true or false value to the isAdult variable accordingly. You can test for null and return some dependent expression in a single line with the ternary operator :, as already given in other answers : (use null to check only for null s values, and null to check for null and undefined) console.log (myVar null myVar. The best image about JavaScript EVER lol. The JavaScript not equal or inequality operator () checks whether two values are not equal and returns a boolean value.

Then we check if a person is an adult based on their age.

We have initialized the variable ‘age’ to 20 and declared ‘isAdult’.

And ‘ expressionIfFalse‘ will be executed if the given expression is false.Įxample of shorthand if in js let age = 20.

The ‘ expressionIfTrue‘ will be executed if the given expression is true.

The ‘ condition‘ is an expression that evaluates to a boolean value.

Syntax of shorthand if condition ? expressionIfTrue : expressionIfFalse

Javascript does not equal shorthand code#

So, we take the decision to use the ternary operator or an if/else statement comes down to personal preference and the specific requirements of the code you are working on. Note, that it’s not recommended to use the question mark operator in this way. Code style: Some developers prefer to use the ternary operator because they find it more aesthetically pleasing or consistent with other parts of their code. In this case we don’t assign a result to a variable, but execute different code depending on the condition.Readability: If we use a ternary operator, it ternary operator can be easier to read than an if/else statement, especially when the condition is simple and the resulting code is short.The conditional operator in JavaScript is. Conciseness: Using the ternary operator allows you to write a conditional statement in a single line, whereas an if/else statement typically requires multiple lines. b:c is not a valid ternary expression (but a newline is acceptable after both the and the : ).In some cases where using the ternary operator can be more concise and easier to read than using an if/else statement In the above code snippet we used the simple way of writing program on Not equal to operator in JavaScript.Why should we use shorthand if instead of if/else statement? NOTE: The Not equal to operator value can be written as a != 30 or a != "30", both gives the same result.īasic way of using Not equal to operator Other way to write Not equal to operator in JavaScript.ĭocument.getElementById(" myId").innerHTML = c

var1 4 var2 '3' Strict equal () Returns true if the operands are equal and of the same type. In the above code snippet we have given same values to the variable a and to the not equal operator, so the result give 'false'. 3 '3' Not equal () Returns true if the operands are not equal. Use the om() function to turn the arguments. In the above code snippet we have given two different values to the variable a and to the not equal operator, so the result gives 'true'.Īssigning same values Assigning 'a' value as 30 and checking the value with '30' in not equal to operator, so the result givesĭocument.getElementById(" myId").innerHTML = ( a != 30) Due to the fact that the objects arguments are not real arrays, not all array methods are accessible. Assigning different values Assigning 'a' value as 30 and checking the value with '10' in not equal to operator, so the result givesĭocument.getElementById(" myId").innerHTML = ( a != 10) The symbolic representation of Not equal operator in JavaScript is !=. If the value of two operands are not equal it returns true. Not equal is an comparison operator which is used to check the value of two operands are equal or not. You can also use +, where a + b is a shorthand for a Summary A comma operator takes two. In the previous post we learnt the Equal opeartor, from this post we are going to learn the Not equal operator in Comparison Operators. It may not be a JavaScript heavy-hitter but I like it anyway.
