parseInt()
function parses a string and returns an integer. Here's an example:
var a = parseInt("007");
The above function converts the string "007" to an integer 7. If the first character in the string can't be converted into a number, then it returns NaN
.
parseInt()
in the convertToInteger
function so it converts the input string str
into an integer, and returns it.
convertToInteger
should use the parseInt()
function
testString: assert(/parseInt/g.test(code), 'convertToInteger
should use the parseInt()
function');
- text: convertToInteger("56")
should return a number
testString: assert(typeof(convertToInteger("56")) === "number", 'convertToInteger("56")
should return a number');
- text: convertToInteger("56")
should return 56
testString: assert(convertToInteger("56") === 56, 'convertToInteger("56")
should return 56');
- text: convertToInteger("77")
should return 77
testString: assert(convertToInteger("77") === 77, 'convertToInteger("77")
should return 77');
- text: convertToInteger("JamesBond")
should return NaN
testString: assert.isNaN(convertToInteger("JamesBond"), 'convertToInteger("JamesBond")
should return NaN');
