JavaScript test for integer / string

Posted on by

I couldn’t find either of these functions that satisfied my edge cases or desire for simplicity so I wrote/adapted some of my own. Feel free to use, modify, distribute without attribution, but I’d be eternally grateful if you did ;)

The test for integer is adapted from this post, which is actually almost spot on, apart from their is_int([0]) returns true, as does any integer in a string.

I’m pretty sure I’ve seen this test for string a hundred times on the internet and in books. It is by far the most robust:

Please let me know if you can break it!

  7. Big Bass Bonanza is a high-volatility slot, meaning wins may not occur frequently, but they can be substantial when they do. The scattered bass has the power to take the player there, offering the following: Like in most other 5×3 slots, Big Bass Bonanza pays out for three or more matching symbols on a payline. The Wild can help you line up winning combos by standing in for paying symbols (not the Scatter). Big Bass Bonanza has two main bonus symbols: the Fisherman and the Scatter. The Fisherman symbol acts as a wild and can substitute for all other symbols except the Scatter to form winning combinations. Landing three or more Scatters triggers the free spins round, where players can win big with multipliers and additional Fisherman symbols. With an RTP of 96.71%, Big Bass Bonanza floats above the average found in many other popular online casino games. Its high volatility, rated 4 out of 5, means wins may be less frequent but more rewarding when they hit. This money game perfectly balances risk and excitement, making it a must-try for gambling enthusiasts in the UK and high rollers specifically!

  18. Head to Miami with the Bigger Bass Bonanza slot by Pragmatic Play. The second game in the series has 5 reels, 4 rows and 12 paylines. Playable from 12p a spin on all devices, it was released in September 2021. Took their time, didn’t they? The Big Bass series has gone through so many iterations that one might have thought we’d have seen a 1000 version by now. Never mind, fish fans, we got it now, and well, it turned out to be about what was expected. Most of the game is regular Big Bass stuff, with a couple of tweaks that put Big Bass Bonanza 1000 into a different league from the bulk of its brethren. Kind of odd tweaks, actually. The 1000 part of the deal would appear to be linked to the 1,000x fish value, but interestingly, the biggest fish is worth just half of the 2,000x top fish money symbol that is theoretically available in the first Big Bass Bonanza slot, putting a slight downer on the experience.

    For a long time, heavy software like Adobe ruled the video editing era. But now, it’s time for changes. When compared to the top 5 video editing software, Alight Motion Mod Apk stands out as a single, one-of-its-kind software with countless features under one banner.
