inRange

Checks if a value is within a specified range.

const result = inRange(value, maximum);
const result = inRange(value, minimum, maximum);

Reference

inRange(value, maximum)

Use inRange when you want to check if a value is within the range from 0 to less than the maximum value. The minimum value is automatically set to 0.

import { inRange } from 'es-toolkit/math';

// Check within the range from 0 to less than 5
const result1 = inRange(3, 5); // result1 is true (0 <= 3 < 5)
const result2 = inRange(5, 5); // result2 is false (5 is not less than 5)
const result3 = inRange(-1, 5); // result3 is false (-1 < 0)

Parameters

• value (number): The value to check.
• maximum (number): The maximum value of the range (exclusive).

Returns

(boolean): Returns true if the value is within the range from 0 (inclusive) to the maximum value (exclusive), otherwise false.

inRange(value, minimum, maximum)

Use inRange when you want to check if a value is within a specified minimum and maximum range.

import { inRange } from 'es-toolkit/math';

// Check within the minimum and maximum range
const result1 = inRange(3, 2, 5); // result1 is true (2 <= 3 < 5)
const result2 = inRange(1, 2, 5); // result2 is false (1 < 2)
const result3 = inRange(5, 2, 5); // result3 is false (5 is not less than 5)

// Can be used with negative ranges
const result4 = inRange(-3, -5, -1); // result4 is true (-5 <= -3 < -1)

Parameters

• value (number): The value to check.
• minimum (number): The minimum value of the range (inclusive).
• maximum (number): The maximum value of the range (exclusive).

Returns

(boolean): Returns true if the value is within the specified range, otherwise false.

Throws

Throws an error if the minimum is greater than or equal to the maximum.
