Lodash _.gte() Method

Author Riya Singh
0 upvote

Introduction

In programming, comparing numerical values is a frequent requirement, particularly when determining if one value is greater than or equal to another. Lodash enhances this aspect of numerical comparison with its _.gte() method. 

Lodash _.gte() Method

This method provides a simple and efficient way to check if one value is greater than or equal to another, enhancing code readability and consistency in comparisons.

Why This Function is Used

The _.gte() (greater than or equal to) function is used for comparing two values to determine if the first is greater than or equal to the second. It's essential in scenarios involving numerical range checks, conditional logic, or sorting operations. By offering a clear and expressive utility for such comparisons, it simplifies and streamlines code that deals with numerical relationships.

Syntax, Parameter and Return Value

Syntax:

_.gte(value, other)

Parameters:

  • value: The value to compare.
     
  • other: The other value to compare against.

Return Value: 

(boolean) - Returns true if value is greater than or equal to other, else false.

Examples 

Basic Numerical Comparison:

  • JavaScript

JavaScript

var _ = require('lodash');

console.log(_.gte(3, 3));

console.log(_.gte(3, 4));

 Output:

true
false


Demonstrates the basic usage of _.gte() for comparing numbers.

Using in Conditional Statements:

  • JavaScript

JavaScript

var score = 75;

if (_.gte(score, 60)) {

 console.log('Passed');

} else {

 console.log('Failed');

}

Output: 

'Passed'


Shows how to use _.gte() in a conditional statement for decision-making.

Range Checking:

  • JavaScript

JavaScript

var age = 18;

if (_.gte(age, 18)) {

 console.log('Eligible');

} else {

 console.log('Not Eligible');

}

Output: 

'Eligible'


An example of using _.gte() for checking eligibility based on age.

Sorting Array Elements:

  • JavaScript

JavaScript

var numbers = [5, 3, 4, 1, 2];

var sortedNumbers = _.sortBy(numbers, (a, b) => _.gte(a, b));

console.log(sortedNumbers);

Output: 

[1, 2, 3, 4, 5]


Demonstrates using _.gte() in sorting an array of numbers.

Frequently Asked Questions

Can _.gte() be used with non-numeric values?

While _.gte() is primarily designed for numerical comparisons, it can technically be used with any types that are comparable in JavaScript. However, it's most meaningful and reliable with numbers.

How does _.gte() handle NaN values?

When comparing with NaN (Not a Number), _.gte() follows JavaScript's comparison rules, and the result will typically be false.

Is _.gte() suitable for array or object comparisons?

_.gte() is not intended for direct comparisons of arrays or objects. It is best used for simple values like numbers or strings, where the concept of "greater than or equal to" is clearly defined.

Conclusion

Lodash's _.gte() method offers an effective and straightforward way to perform greater-than-or-equal-to comparisons. It is a valuable tool for numerical comparisons, making conditional logic and range checks more expressive and easier to understand.
